ubiquitination by UCH-L1 is involved in ischemia-reperfusion stress
malfunction
-
UCH-L1 is highly expressed in Burkitt's lymphoma and is up-regulated upon infection of B lymphocytes with Epstein-Barr virus, EBV. Selective up-regulation of the ubiquitin C-terminal hydrolase UCH-L1 in a variety of metastatic tumours contributes to the malignant phenotype
malfunction
UCH-L1 is up-regulated in injured arteries, via posttranscriptional regulation, and local gene delivery of UCH-L1 inhibited vascular lesion formation with suppression of inflammatory responses in vasculature. ERK activation also contributes to the growth inhibitory effect of UCH-L1 in TNFalpha-inflamed vascular smooth muscle cells

-
UCH enzymes and human malignancies are closely correlated with roles of UCH enzymes in oncogenesis, UCH-L1 enhances tumor cell invasion and migration capability via the Akt-mediated pathway, overview. Dysfunction of UCH-L1 hydrolase activity can lead to an accumulation of alpha-synuclein and neurofibrillary tangles, which links to Parkinson's disease and Alzheimer's disease, respectively. Increased levels of both UCH-L1 and UCH-L3 mRNA are associated with early tumor recurrence of invasive breast cancer and poor prognosis. UCH37 activity is up-regulated in cervical carcinoma biopsies as well as cell lines. UCH-L1 levels are high in various types of malignancies: acute lymphoblastic leukemia, non-small cell lung cancer, neuroblastoma, pancreatic, prostate, medullary thyroid, esophageal, colorectal and renal carcinomas, although lowered in cervical carcinomas
malfunction
-
Uch-L1 is associated with Parkinson's disease, as alpha2-adrenergic receptor interacting protein. alpha2-Adrenergic receptor agonist-mediated activation of p44/42MAP kinase is drastically decreased in the presence of Uch-L1. Stimulation of recombinantly UCH-L1 expressing HEK-293 cells prior lysis with norepinephrine, yohimbine, phentolamine or moxonidine does also not significantly affect the interaction, as well as co-transfection of arrestin-3 or spinophilin-(Phe151-Lys446)

physiological function
UCH-L1 appears to be a multi-functional protein and exerts cell type and/or tissue specific actions
physiological function
-
UCH-L1 plays a crucial role in regulating certain signalings. UCH-L1 forms endogenous complexes with beta-catenin, stabilizes it and up-regulates beta-catenin/TCF/Lef-dependent transcription. Reciprocally, as indicated, beta-catenin/TCF/Lef signaling up-regulates the expression of endogenous UCH-L1 mRNA and protein. UCH-L1 is responsible for hydrolyzing carboxyl terminal esters and amides of Ub. Additionally, it possesses ubiquitin ligase activity and functions as a mono-ubiquitin stabilizer, which is independent of enzymatic activity, and is also involved in the co-translational processing of pro-ubiquitin and ribosomal proteins translated as ubiquitin fusions. UCH-L3 is a kind of ubiquitin-protein hydrolase involved in the processing of both ubiquitin precursors and ubiquitinated substrates, generating free monomeric ubiquitin. UCH37, different from other UCH members, is responsible for the Ub isopeptidase activity in the 19S proteasome regulatory complex, overview. Upregulation of TGF-beta signaling by UCH37

UCH-L1 function is required for synaptic plasticity and is itself regulated by synaptic activity. UCH-L1 activity is required for NMDA-induced up-regulation of free monomeric ubiquitin. UCH-L1 can also bind to ubiquitin and act as a ubiquitin stabilizer to prevent its degradation by lysosomes. UCH-L1 regulates spine morphology and density

UCHL1 is a component of the ubiquitin system, and the UCH-L1-dependent apoptosis is important for spermatogenesis. UCH-L1 plays an important role, possibly in association with Jab1 and p27Kip1, in selective elimination of abnormal oocytes during mouse prepubertal development
physiological function
-
high glucose increases the TGF-betaR1 protein expression via the PI3K-UCHL5 pathway in mesangial cells; UCHL5 is required for high glucose-induced reduction of TGFbetaR1 protein ubiquitination, p21WAF1 protein expression, cell hypertrophy and fibronectin protein expression
physiological function

ubiquitin C-terminal hydrolase UCH-L3 is upregulated in normal or non-metastatic prostate cancer cells and is downregulated in metastatic prostate cancer cell lines. Knockdown of UCH-L3 in normal prostate cell line RWPE1 promotes epithelial-to-mesenchymal transition, an important process for cancer cell invasion and metastasis. The induction of epithelial-to-mesenchymal transition by UCH-L3 knockdown results in an increase of cell migration and invasion. Overexpression of UCH-L3 in highly metastatic prostate cancer cell line PC3 reverses epithelial-to-mesenchymal transition but an active site mutant of UCH-L3 does not
physiological function
expression of isoform UCHL1 is elevated in osteosarcoma compared with normal bone tissue. UCHL1 expression level is correlated with tumor maximum diameter, high rate of lung metastases and short survival time. Knockdown of UCHL1 in osteosarcoma cell MG-63 inhibits cell proliferation and significantly increases cell population in the G1 phase. Cyclins promoting G1/S phase transition are reduced after UCHL1 knockdown, including cell cycle regulator cyclin D1, cyclin E1 and CDK6. Inhibition of UCHL1 in MG-63 cells dramatically induces cell apoptosis. Downregulation of UCHL1 in MG-63 significantly inhibits cell invasion. There is a positive correlation between UCHL1 expression level and the Akt and ERK phosphorylation status
physiological function
-
over-expression of dUCH in the eye imaginal discs induces a rough eye phenotype in the adult, at least partly resulting from the induction of caspase-dependent apoptosis followed by compensatory proliferation. The over-expression of dUCH specifically impairs R7 photoreceptor cell differentiation with a reduction in activated extracellular-signal regulated kinase signals. The dUCH-induced rough eye phenotype is rescued by co-expression of the sevenless gene or the Draf gene, a downstream component of the mitogen-activated protein kinase (MAPK) cascade
physiological function
-
compared with controls, CO-poisoned patients have significantly elevated serum levels of UCH-L1 at each time point after poisoning. There are significantly higher levels of UCH-L1 in CO-poisoned patients with a lower Glasgow coma scale (GCS) score as well as in those with a poor 6-month outcome dichotomized Glasgow outcome scale (GOS)
physiological function
-
RNAi-mediated knockdown of the ubiquitin hydrolase, USP22, results in 2fold increase in monoubiquitinated histone H2B, and 2fold decrease in transcriptional elongation at IRF1. USP22 depletion diminishes 3'-end cleavage/polyadenylation by 2- to 3fold. The polyadenylation factor CPSF73 is not effectively recruited, and serine 2 phosphorylation of the C-terminal domain of RNA polymerase II is also disrupted. Results suggest that ubiquitinated histone H2B helps recruit polyadenylation factors to STAT1-activated genes
physiological function
-
melanoma cells show a a widespread loss or reduced expression of ubiquitin C-terminal hydrolase UCHL1, which is directly correlated with promoter DNA hypermethylation. The subset of melanoma cells, which still express UCHL1, shows altered growth properties and tolerances against reactive oxygen species as compared to UCHL1-negative cells
physiological function
-
UCH-L1 physically interacts with CDK1, CDK4, and CDK5, enhancing their kinase activity
physiological function
-
both biomarkers UCH-L1 and glial fibrillary acidic protein(GFAP) discriminate between traumatic brain injury (TBI) patients with intracranial lesions on CT scan from those without such lesions. GFAP measures are significantly more sensitive and specific than UCH-L1. The addition of UCH-L1 values marginally improved upon GFAP alone in predicting dichotomized Glasgow Outcome Scale Extended (GOS-E) at 3 months after injury
physiological function
-
isoform UCHL1 physically interacts with high affinity choline transporter CHT, which is a key protein regulating Ach re-synthesis. Reduction of UCHL1 by siRNA gene knockdown significantly increases polyubiquitinated CHT and decreased native CHT protein level, but does not affect CHT mRNA expression. Gene knockdown of UCHL1 significantly reduces cytosolic CHT but has no significant effect on membrane CHT level

UCH-L1 can hydrolyze isopeptide bonds between the C-terminal glycine of Ub and the alpha- or gamma-amino group of lysine on the target proteins. UCH-L3 recognizes and hydrolyzes isopeptide bonds at the C-terminal glycine of either ubiquitin or Nedd8, a ubiquitin-like protein. It shows no ligase activity. UCH-L3 can interact with Lys48-linked ubiquitin dimers to protect it from degradation and meanwhile to inhibit its hydrolase activity, D33 and C95 are essential for the interaction with di-ubiquitin. Neither UCH37 alone nor the UCH37-Adrm1 or UCH37-Adrm1-hRpn2 complexes can hydrolyse Lys48-linked di-ubiquitin efficiently, rather, their incorporation into the 19S complex is required to enable UCH37 to process large ubiquitin protein conjugates such as di-ubiquitin

Both enzymes cleave ubiquitin from N-epsilon linked lysine or N-alpha-linked lysine equally well. Neither can cleave the Ub-K48 Ub bond, but both can cleave lysine from the C-terminal of this conjugate. UCHL3 can readily cleave a wide variety of peptides from the C-terminus of ubiquitin if the peptides are less than 20 residues, UCHL1/PGP 9.5 is at least a hundred times less active in this

UCH-L1 can hydrolyze isopeptide bonds between the C-terminal glycine of Ub and the alpha- or gamma-amino group of lysine on the target proteins. UCH-L3 recognizes and hydrolyzes isopeptide bonds at the C-terminal glycine of either ubiquitin or Nedd8, a ubiquitin-like protein. It shows no ligase activity. UCH-L3 can interact with Lys48-linked ubiquitin dimers to protect it from degradation and meanwhile to inhibit its hydrolase activity, D33 and C95 are essential for the interaction with di-ubiquitin. Neither UCH37 alone nor the UCH37-Adrm1 or UCH37-Adrm1-hRpn2 complexes can hydrolyse Lys48-linked di-ubiquitin efficiently, rather, their incorporation into the 19S complex is required to enable UCH37 to process large ubiquitin protein conjugates such as di-ubiquitin

class of 3-amino-2-keto-7H-thieno[2,3-b]pyridin-6-one derivatives are moderately potent UCH-L1 inhibitors. Carboxylate at the 5-position and the 6-pyridinone ring are necessary for inhibitory activity. Inhibitory activity is dependent on the nature of the ketone substituent at the 2-position, with 4-Me-Ph and 2-naphthyl being best. Compounds are uncompetitive inhibitors of UCH-L1, binding only to the Michaelis-complex and not to free enzyme. Active compounds are selective for UCH-L1, exhibiting no inhibition of other cysteine hydrolases or cytotoxicity in serum starved N2A cells. Not inhibited by compound 9, 17, 19, 22, 24, 27, 28, 29, 30, 32 and 33

embryo, expression pattern in the ventricular zone changes between embryonic day 14 and 16, which corresponds to the transition from neurogenesis to gliogenesis. At embryonic day 14, UCH-L1 is highly expressed in the ventricular zone, where neurogenesis actively occurs, whereas its expression is prominent in the cortical plate at embroynic day 16. UCH-L1 is very weakly detected in the ventricular zone at embryonic day 16, which corresponds to the start of gliogenesis. UCH-L1 spatially mediates and enhances neurogenesis in the embryonic brain by regulating progenitor cell morphology; embryonic, UCH-L1 expression in the ventricular zone changes during neurogenesis and gliogenesis, high expression level in cortical plate and ventricular zone, overview

brain, expression pattern in the ventricular zone changes between embryonic day 14 and 16, which corresponds to the transition from neurogenesis to gliogenesis. At embryonic day 14, UCH-L1 is highly expressed in the ventricular zone, where neurogenesis actively occurs, whereas its expression is prominent in the cortical plate at embroynic day 16. UCH-L1 is very weakly detected in the ventricular zone at embryonic day 16, which corresponds to the start of gliogenesis. UCH-L1 spatially mediates and enhances neurogenesis in the embryonic brain by regulating progenitor cell morphology

; down regulation of UCHL1 is detected immediately after oxygen-glucose deprivation treatment and its expression is subsequently restored and increased 6 h after oxygen-glucose deprivation treatment as well as during reoxygenation. A lower level of UCHL1 is detected only in apoptotic cells with severe loss of mitochondrial membrane potential. Down-regulation of endogenous UCHL1 by antisense cDNA in mouse N2a neuroblastoma cells increased the cells sensitivity to oxygen-glucose deprivation. This down-regulation of endogenous UCHL1 leads to the accumulation of p27, suggesting that UCHL1 is an essential gene to maintain cell homeostasis under normal growth and oxidative stress conditions

ubiquitination
-
monoubiquitination is a posttranslational modification of UCH-L1 that controls the function of UCH-L1. It may occur reversibly to a lysine residue near the active site, probably K157, of UCH-L1. This modification restricts enzyme activity by preventing binding to the ubiquitinated targets, and permanent mono-ubiquitination, as mimicked by a ubiquitin-UCH-L1 fusion, inhibits UCH-L1 in its capacity to increase free ubiquitin levels. However, the lifetime of this modification on UCH-L1 is regulated by auto-deubiquitination
