Protein kinase C iota type is an enzyme that in humans is encoded by the PRKCI gene.[1][2][3]
This gene encodes a member of the protein kinase C (PKC) family of serine/threonine protein kinases. The PKC family comprises at least eight members, which are differentially expressed and are involved in a wide variety of cellular processes. This protein kinase is calcium-independent and phospholipid-dependent. It is not activated by phorbolesters or diacylglycerol. This kinase 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. This kinase is found to be necessary for BCL-ABL-mediated resistance to drug-induced apoptosis and therefore protects leukemia cells against drug-induced apoptosis. There is a single exon pseudogene mapped on chromosome X.[3]
Interactions
PRKCI has been shown to interact with Glyceraldehyde 3-phosphate dehydrogenase,[4] Centaurin, alpha 1,[5] Phosphoinositide-dependent kinase-1,[6] FRS2,[7] SMG1 (gene),[8] Sequestosome 1 and PARD3.[9][10]
