Parkin-mediated ubiquitination regulates phospholipase C-γ1
Mutations in parkin cause autosomal recessive forms of Parkinson's disease (PD), with an early age of onset and similar pathological phenotype to the idiopathic disease. Parkin has been identified as an E3 ubiquitin ligase that mediates different types of ubiquitination, which has made the search for substrates an intriguing possibility to identify pathological mechanisms linked to PD. In this ...

متن کاملBenzene-mediated protein kinase C activation.
Extracellular ligands transfer information into the cell through several pathways that operate in an integrated fashion. Protein kinase C, and enzyme that plays a pivotal role in signal transduction, is the molecular target for tumor promoters from the series of phorbol esters. A number of structurally unrelated tumor promoters also enhance protein kinase C, interacting or not interacting with ...
متن کاملAhnak protein activates protein kinase C (PKC) through dissociation of the PKC-protein phosphatase 2A complex.
We have previously reported that central repeated units (CRUs) of Ahnak act as a scaffolding protein networking phospholipase Cgamma and protein kinase C (PKC). Here, we demonstrate that an Ahnak derivative consisting of four central repeated units binds and activates PKC-alpha in a phosphatidylserine/1,2-dioleoyl-sn-glycerol-independent manner. Moreover, NIH3T3 cells expressing the 4 CRUs of A...
متن کاملPlatelet-derived growth factor stimulates protein kinase D through the activation of phospholipase Cgamma and protein kinase C.
Platelet-derived growth factor (PDGF) stimulates protein kinase D (PKD) in a time- and dose-dependent manner. We have used a series of PDGF receptor mutants that display a selective impairment of the binding of SH2-containing proteins (GTPase-activating protein, SHP-2, phospholipase Cgamma (PLCgamma), or phosphatidylinositol 3'-kinase (PI3K)) to show that Tyr-1021, the PLCgamma-binding site, is...
