Background
Protein kinase C (PKC) is a family of serine- and threonine-specific protein kinases that can be activated by calcium and the second messenger diacylglycerol. PKC family members phosphorylate a wide variety of protein targets and are known to be involved in diverse cellular signaling pathways. PKC family members also serve as major receptors for phorbol esters, a class of tumor promoters. Each member of the PKC family has a specific expression profile and is believed to play a distinct role in cells. PRKCI (Protein Kinase C Iota), a calcium- and diacylglycerol-independent serine/threonine-protein kinase that plays a general protective role against apoptotic stimuli and is involved in NF-kappa-B activation, cell survival, differentiation and polarity, and contributes to the regulation of microtubule dynamics in the early secretory pathway. PRKCI is necessary for BCL-ABL-mediated resistance to drug-induced apoptosis and therefore protects leukemia cells against drug-induced apoptosis. In cultured neurons, PRKCI prevents amyloid beta protein-induced apoptosis by interrupting cell death process at a very early step. In glioblastoma cells, PRKCI may function downstream of phosphatidylinositol 3-kinase (PI(3) K) and PDPK1 in the promotion of cell survival by phosphorylating and inhibiting the pro-apoptotic factor BAD. PRKCI can be recruited to vesicle tubular clusters (VTCs) by direct interaction with the small GTPase RAB2, where this kinase phosphorylates glyceraldehyde-3-phosphate dehydrogenase (GAPD/GAPDH) and plays a role in microtubule dynamics in the early secretory pathway.

Application Notes
Recombinant PRKCI protein is suitable for use in in enzyme kinetics, inhibitor screening, and selectivity profiling.
