PRKCD Summary & Protein Information

PRKCD Background

Gene Summary: 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 distinct roles in cells. The protein encoded by PRKCD gene is one of the PKC family members. Studies both in human and mice demonstrate that this kinase is involved in B cell signaling and in the regulation of growth, apoptosis, and differentiation of a variety of cell types. Alternatively spliced transcript variants encoding the same protein have been observed. [provided by RefSeq, Jul 2008]

Catalytic activity: ATP + a protein = ADP + a phosphoprotein.; ATP + a [protein]-L-tyrosine = ADP + a [protein]-L-tyrosine phosphate. {ECO:0000255|PROSITE-ProRule:PRU10027}.
Enzyme regulation: ENZYME REGULATION: Novel PKCs (PRKCD, PRKCE, PRKCH and PRKCQ) are calcium-insensitive, but activated by diacylglycerol (DAG) and phosphatidylserine. Three specific sites; Thr-507 (activation loop of the kinase domain), Ser-645 (turn motif) and Ser-664 (hydrophobic region), need to be phosphorylated for its full activation. Activated by caspase-3 (CASP3) cleavage during apoptosis. After cleavage, the pseudosubstrate motif in the regulatory subunit is released from the substrate recognition site of the catalytic subunit, which enables PRKCD to become constitutively activated. The catalytic subunit which displays properties of a sphingosine-dependent protein kinase is activated by D-erythro-sphingosine (Sph) or N,N-dimethyl-D-erythrosphingosine (DMS) or N,N,N-trimethyl-D-erythrosphingosine (TMS), but not by ceramide or Sph-1-P and is strongly inhibited by phosphatidylserine (By similarity). {ECO:0000250}.
Subunit structure: Interacts with PDPK1 (via N-terminal region), RAD9A, CDCP1, MUC1 and VASP. {ECO:0000269|PubMed:11781095, ECO:0000269|PubMed:11877440, ECO:0000269|PubMed:12628935, ECO:0000269|PubMed:15851033, ECO:0000269|PubMed:16940418}.
Domain: The C1 domain, containing the phorbol ester/DAG-type region 1 (C1A) and 2 (C1B), is the diacylglycerol sensor.; The C2 domain is a non-calcium binding domain. It binds proteins containing phosphotyrosine in a sequence-specific manner.
Subcellular location: Cytoplasm. Cytoplasm, perinuclear region. Nucleus. Endoplasmic reticulum. Mitochondrion. Cell membrane; Peripheral membrane protein.
Post-translational: Autophosphorylated and/or phosphorylated at Thr-507, within the activation loop; phosphorylation at Thr-507 is not a prerequisite for enzymatic activity. Autophosphorylated at Ser-299, Ser-302 and Ser-304. Upon TNFSF10/TRAIL treatment, phosphorylated at Tyr-155; phosphorylation is required for its translocation to the endoplasmic reticulum and cleavage by caspase-3. Phosphorylated at Tyr-313, Tyr-334 and Tyr-567; phosphorylation of Tyr-313 and Tyr-567 following thrombin stimulation potentiates its kinase activity. Phosphorylated by protein kinase PDPK1; phosphorylation is inhibited by the apoptotic C-terminal cleavage product of PKN2. {ECO:0000269|PubMed:11781095, ECO:0000269|PubMed:15774464, ECO:0000269|PubMed:17570831, ECO:0000269|PubMed:17603046, ECO:0000269|PubMed:19801500}.; Proteolytically cleaved into a catalytic subunit and a regulatory subunit by caspase-3 during apoptosis which results in kinase activation. {ECO:0000250}.
Involvement in disease: DISEASE: Autoimmune lymphoproliferative syndrome 3 (ALPS3) [MIM:615559]: A primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B-cells is usually in the normal range, but can be low. CVID9 patients have B-cell deficiency and severe autoimmunity. {ECO:0000269|PubMed:23319571}. Note=The disease is caused by mutations affecting the gene represented in this entry.
Sequence similarity: Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family. PKC subfamily. {ECO:0000305}.; Contains 1 AGC-kinase C-terminal domain. {ECO:0000305}.; Contains 1 C2 domain. {ECO:0000305}.; Contains 2 phorbol-ester/DAG-type zinc fingers. {ECO:0000255|PROSITE-ProRule:PRU00226}.; Contains 1 protein kinase domain. {ECO:0000255|PROSITE-ProRule:PRU00159}.
