CC -!- FUNCTION: Calcium-independent, phospholipid- and diacylglycerol (DAG)-
CC dependent serine/threonine-protein kinase that is involved in the
CC regulation of cell differentiation in keratinocytes and pre-B cell
CC receptor, mediates regulation of epithelial tight junction integrity
CC and foam cell formation, and is required for glioblastoma proliferation
CC and apoptosis prevention in MCF-7 cells. In keratinocytes, binds and
CC activates the tyrosine kinase FYN, which in turn blocks epidermal
CC growth factor receptor (EGFR) signaling and leads to keratinocyte
CC growth arrest and differentiation. Associates with the cyclin CCNE1-
CC CDK2-CDKN1B complex and inhibits CDK2 kinase activity, leading to RB1
CC dephosphorylation and thereby G1 arrest in keratinocytes. In
CC association with RALA activates actin depolymerization, which is
CC necessary for keratinocyte differentiation. In the pre-B cell receptor
CC signaling, functions downstream of BLNK by up-regulating IRF4, which in
CC turn activates L chain gene rearrangement. Regulates epithelial tight
CC junctions (TJs) by phosphorylating occludin (OCLN) on threonine
CC residues, which is necessary for the assembly and maintenance of TJs.
CC In association with PLD2 and via TLR4 signaling, is involved in
CC lipopolysaccharide (LPS)-induced RGS2 down-regulation and foam cell
CC formation. Upon PMA stimulation, mediates glioblastoma cell
CC proliferation by activating the mTOR pathway, the PI3K/AKT pathway and
CC the ERK1-dependent phosphorylation of ELK1. Involved in the protection
CC of glioblastoma cells from irradiation-induced apoptosis by preventing
CC caspase-9 activation. In camptothecin-treated MCF-7 cells, regulates
CC NF-kappa-B upstream signaling by activating IKBKB, and confers
CC protection against DNA damage-induced apoptosis.

CC -!- ACTIVITY REGULATION: Novel PKCs (PRKCD, PRKCE, PRKCH and PRKCQ) are
CC calcium-insensitive, but activated by diacylglycerol (DAG) and
CC phosphatidylserine. Three specific sites; Thr-513 (activation loop of
CC the kinase domain), Thr-656 (turn motif) and Ser-675 (hydrophobic
CC region), need to be phosphorylated for its full activation.
