3.1.3.36 malfunction At5PTase7 mutants show reduced salt tolerance and increased salt stress response, phenotype, overview 716624 3.1.3.36 malfunction both knockdown of SHIP2 expression and acute production of PI(3,4,5)P3 shorten clathrin-coated pits lifetime by enhancing the rate of pit maturation 715707 3.1.3.36 malfunction depletion of SHIP2 attenuates cell polarization and migration, which is rescued by wild-type SHIP2 but not by a mutant defective in RhoA binding. In addition, the depletion of SHIP2 impairs the proper localization of phosphatidylinositol 3,4,5-trisphosphate, which is not restored by a mutant defective in RhoA binding 732478 3.1.3.36 malfunction enzyme depletion exclusively impairs apical secretory transport in intestinal epithelia. Enzyme loss leads to increased phosphatidylinositol 4,5-bisphosphate levels and overaccumulation of actin structures as well as intracellular accumulation of ARF-6 and UNC-16 751176 3.1.3.36 malfunction enzyme knockdown results in increased proliferation and anchorage-independent growth of melanocytes 730456 3.1.3.36 malfunction excess amounts of SHIP2 may be related, at least in part, to brain dysfunction in insulin resistance with type 2 diabetes. A dominant-negative mutant of SHIP2, expressed in cultured neurons, causes insulin signaling augmentation. Inhibition of SHIP2 ameliorates the impairment of hippocampal synaptic plasticity and memory formation in db/db mice -, 716225 3.1.3.36 malfunction expression of SKIP in C2C12 cells results in a slight decrease in myogenin expression and Akt phosphorylation after 48 h, with a marked decrease in MHC expression after 72 h. Expression of a phosphatase dead mutant in C2C12 cells does not show any effect 729995 3.1.3.36 malfunction in absence of dOCRL, several essential components of the cleavage furrow are found to be incorrectly localized on giant cytoplasmic vacuoles rich in PI(4,5)P2 and in endocytic markers 714782 3.1.3.36 malfunction in cells knocked down for OCRL, transfection of enzymatically active EGFP-OCRL-a (but not of a phosphatase-dead enzyme) decreases the levels of intracellular Listeria monocytogenes and of actin associated with invading bacteria 732045 3.1.3.36 malfunction in SHIP2 siRNA transfected cells, insulin treatment does not lead to alter the PIP3 level in contrast to SKIP or PTEN silenced cells. Results demonstrate that SHIP2 in contrast to SKIP is not involved in the regulation of insulin signaling in C2C12 cells 732083
