3.2.2.6	evolution	the CD38-cADPR signaling system is conserved during vertebrate evolution, phylogenetic tree	732501	
3.2.2.6	malfunction	ablation of the CD38 gene in mice causes multiple physiological defects, including impaired oxytocin release, that result in altered social behavior	731296	
3.2.2.6	malfunction	CD38 knockout mice manifest multiple defects relating to Ca2+ signaling, including that of insulin secretion, hormonal signaling in pancreatic acinar cells, migration of dendritic cell precursors, bone resorption, airway responsiveness, alpha-adrenoceptor signaling in aorta, cardiac hypertrophy, susceptibility to bacterial infection, as well as social behavior in mice through modulation of oxytocin secretion	716910	
3.2.2.6	malfunction	CD38 reductions lead to microglial apoptosis. inhibition of CD38/cADPR-dependent signaling by CD38 silencing or 8-bromo-cADPR, a ryanodine receptor antagonist, produced significant ATP release from BV2 microglia. Cx43 small interfering RNA and Cx43 hemichannel blocker 18-alpha-glycyrrhetinic acid completely prevented the CD38 silencing or 8-bromo-cADPR-induced ATP release. Prevention of the ATP release might also be due to P2X7 receptor antagonists. Key role of ATP release in the microglial apoptosis induced by decreased CD38/cADPR-dependent signaling, overview	731882	
3.2.2.6	additional information	D226/Q226 and K129 residues of the two CD38 enzyme are the ADP-ribosylation sites. 6-Alkyne-F-araNAD, 6-alkyne-NAD, and Rh-N3 are used in the labeling reactions of CD38 wild-type and mutants, overview	731119	
3.2.2.6	additional information	invariant glutamate 218 identified is the catalytic residue of the enzyme, Structure homology modelling, overview	732691	
3.2.2.6	additional information	structure-function analysis, overview. The enzyme catalyzes the formation of beta-1'-O-methyl ADP-ribose in presence of methanol, solvolysis does not affect the overall turnover rate of NAD+ by the wild-type enzyme. Precise role of key conserved active site residues Trp118, Glu138, Asp147, Trp181 and Glu218, effects of experiments with neutral (methanol) and ionic (azide, formate) nucleophiles. Binding of 2'-fluorinated analogs of NAD+ and trappping of the reaction intermediate, detailed overview. Catalytic residue Glu138 is part of the TLEDTL signature domain, Asp147 is a highly conserved residue in the enzyme and is important for the catalytic parameters. Cooperative contribution of Trp118 and Trp181 to catalysis	731357	
3.2.2.6	additional information	structure-function relationship anaysis, overview. Covalent intermediates are formed with the catalytic residue, Glu226	731296	
3.2.2.6	physiological function	CD38 is an ectoenzyme that consumes NAD+ to produce cyclic ADP-ribose, a potent agonist of ryanodine receptors. Basal CD38/cyclic ADP-ribose-dependent signaling plays a key role in ATP release, which mediates basal survival of microglia, overview	731882	
3.2.2.6	physiological function	CD38 is an NAD+-metabolizing enzyme in mammals, a type II transmembrane protein that converts NAD+ primarily to adenosine diphosphate ribose and a small amount of cyclic adenosine diphosphate ribose. The major enzymatic function of the enzyme is to hydrolyze extracellular rather than intracellular NAD+	731987	
3.2.2.6	physiological function	in cultured macrophages, lipopolysaccharide LPS can upregulate CD38 expression in time- and dose-dependent manner. Knocking down or blockade of CD38 in macrophages inhibits LPS-induced macrophage M1 polarization accompanied by diminished NF-kappaB signaling activation. In a mouse model with LPS-induced acute kidney injury, blocking CD38 with quercetin significantly relieves kidney dysfunction, kidney pathological changes as well as inflammatory cell accumulation	750282	
3.2.2.6	physiological function	leukocyte antigen CD38 expression is an early marker of all-trans retinoic acid-stimulated differentiation in the leukemic cell line HL-60 where CD38 promotes induced myeloid maturation when overexpressed. The ability of CD38 to propel all-trans retinoic acid-induced myeloid differentiation and G1/0 arrest is unimpaired by loss of its ectoenzymeactivity	714921	
3.2.2.6	physiological function	senescent cells do not have high expression of CD38. The senescent associated secretory phenotype factors secreted by senescent cells induce CD38 mRNA and protein expression and increase CD38-NADase activity in non-senescent cells such as endothelial cells or bone marrow derived macrophages	749830	
3.2.2.6	physiological function	the enzyme is a signaling enzyme responsible for catalyzing the synthesis of cyclic ADP ribose (cADPR) and nicotinic acid adenine dinucleotide phosphate, both are universal Ca2+ messenger molecules	731296
