Also known as PKCβ

Summary

PRKCB (protein kinase C beta, HGNC:9395) is a protein-coding gene on chromosome 16p12.2-p12.1, encoding Protein kinase C beta type (P05771). Calcium-activated, phospholipid- and diacylglycerol (DAG)-dependent serine/threonine-protein kinase involved in various cellular processes such as regulation of the B-cell receptor (BCR) signalosome, oxidative stress-induced apoptosis, androgen receptor-dependent transcription r….

Protein kinase C (PKC) is a family of serine- and threonine-specific protein kinases that can be activated by calcium and 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. The protein encoded by this gene is one of the PKC family members. This protein kinase has been reported to be involved in many different cellular functions, such as B cell activation, apoptosis induction, endothelial cell proliferation, and intestinal sugar absorption. Studies in mice also suggest that this kinase may also regulate neuronal functions and correlate fear-induced conflict behavior after stress. Alternatively spliced transcript variants encoding distinct isoforms have been reported.

Function. Calcium-activated, phospholipid- and diacylglycerol (DAG)-dependent serine/threonine-protein kinase involved in various cellular processes such as regulation of the B-cell receptor (BCR) signalosome, oxidative stress-induced apoptosis, androgen receptor-dependent transcription regulation, insulin signaling and endothelial cells proliferation. Plays a key role in B-cell activation by regulating BCR-induced NF-kappa-B activation. Mediates the activation of the canonical NF-kappa-B pathway (NFKB1) by direct phosphorylation of CARD11/CARMA1 at ‘Ser-559’, ‘Ser-644’ and ‘Ser-652’. Phosphorylation induces CARD11/CARMA1 association with lipid rafts and recruitment of the BCL10-MALT1 complex as well as MAP3K7/TAK1, which then activates IKK complex, resulting in nuclear translocation and activation of NFKB1. Plays a direct role in the negative feedback regulation of the BCR signaling, by down-modulating BTK function via direct phosphorylation of BTK at ‘Ser-180’, which results in the alteration of BTK plasma membrane localization and in turn inhibition of BTK activity. Involved in apoptosis following oxidative damage: in case of oxidative conditions, specifically phosphorylates ‘Ser-36’ of isoform p66Shc of SHC1, leading to mitochondrial accumulation of p66Shc, where p66Shc acts as a reactive oxygen species producer. Acts as a coactivator of androgen receptor (AR)-dependent transcription, by being recruited to AR target genes and specifically mediating phosphorylation of ‘Thr-6’ of histone H3 (H3T6ph), a specific tag for epigenetic transcriptional activation that prevents demethylation of histone H3 ‘Lys-4’ (H3K4me) by LSD1/KDM1A. In insulin signaling, may function downstream of IRS1 in muscle cells and mediate insulin-dependent DNA synthesis through the RAF1-MAPK/ERK signaling cascade. Participates in the regulation of glucose transport in adipocytes by negatively modulating the insulin-stimulated translocation of the glucose transporter SLC2A4/GLUT4. Phosphorylates SLC2A1/GLUT1, promoting glucose uptake by SLC2A1/GLUT1. Under high glucose in pancreatic beta-cells, is probably involved in the inhibition of the insulin gene transcription, via regulation of MYC expression. In endothelial cells, activation of PRKCB induces increased phosphorylation of RB1, increased VEGFA-induced cell proliferation, and inhibits PI3K/AKT-dependent nitric oxide synthase (NOS3/eNOS) regulation by insulin, which causes endothelial dysfunction. Also involved in triglyceride homeostasis. Phosphorylates ATF2 which promotes cooperation between ATF2 and JUN, activating transcription. Phosphorylates KLHL3 in response to angiotensin II signaling, decreasing the interaction between KLHL3 and WNK4. Phosphorylates and activates LRRK1, which phosphorylates RAB proteins involved in intracellular trafficking. Acts as an activator of ferroptosis by mediating phosphorylation and activation of ACSL4. Also stimulates ferroptosis propagation by catalyzing phosphorylation of FOXK1, thereby promoting LGALS13 secretion.

Subunit / interactions. Interacts with PDPK1/PDK1. Interacts in vitro with PRKCBP1. Interacts with PHLPP1 and PHLPP2; both proteins mediate its dephosphorylation. Interacts with KDM1A/LSD1, PKN1 and AR.

Subcellular location. Cytoplasm. Nucleus. Membrane.

Post-translational modifications. Phosphorylation on Thr-500 within the activation loop renders it competent to autophosphorylate. Subsequent autophosphorylation of Thr-642 maintains catalytic competence, and autophosphorylation on Ser-661 appears to release the kinase into the cytosol. Autophosphorylation on other sites i.e. in the N-terminal and hinge regions have no effect on enzyme activity. Phosphorylation at Tyr-662 by SYK induces binding with GRB2 and contributes to the activation of MAPK/ERK signaling cascade.

Activity regulation. Classical (or conventional) PKCs (PRKCA, PRKCB and PRKCG) are activated by calcium and diacylglycerol (DAG) in the presence of phosphatidylserine. Three specific sites; Thr-500 (activation loop of the kinase domain), Thr-642 (turn motif) and Ser-661 (hydrophobic region), need to be phosphorylated for its full activation. Specifically inhibited by enzastaurin (LY317615).

Cofactor. Binds 3 Ca(2+) ions per subunit. The ions are bound to the C2 domain.

Similarity. Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. PKC subfamily.

A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.

Cancer significance

From intOGen — cancer-driver classification: activating (oncogene-like) across 4 cancer types — DLBCLNOS, HNSC, PRAD, STAD.

intOGen’s role is a computational inference from cohort mutation patterns and may diverge from the gene’s curated/literature role; read it alongside the evidence above.

  • Targeted by drugs: Enzastaurin, Ingenol Mebutate, Ruboxistaurin
  • Disease cohort memberships (association, not causation — diseases whose associated-gene cohort lists this gene; a subset are also under Associated diseases): adult T-cell leukemia/lymphoma
  • Pharmacogenomically associated drugs (drugs whose metabolism/response is associated with variants in this gene (PharmGKB) — not drugs that target it): Medetomidine
