PRKCI (Protein kinase C iota type) is a protein kinase, an enzyme that switches other proteins on by adding phosphate groups. The public catalogues list it as a drug target, and an approved or late-stage drug is recorded against it. Tied to Leukaemia, Myeloproliferative neoplasms, Systemic mastocytosis and 1 more.
Calcium- and diacylglycerol-independent serine/ threonine-protein kinase that plays a general protective role against apoptotic stimuli, 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. Is necessary for BCR-ABL oncogene-mediated resistance to apoptotic drug in leukaemia cells, protecting leukaemia cells against drug-induced apoptosis. In cultured neurons, prevents amyloid beta protein-induced apoptosis by interrupting cell death process at a very early step.
Open Targets scores its association with cancer at 0.67 (direct and indirect evidence; datatypes literature 0.97, genetic association 0.54, clinical 0.92).

No product in this corpus aims at PRKCI yet. Kinases are switched on by binding ATP inside the cell, so most drugs are small molecules shaped to plug that ATP pocket.
Broadly expressed or essential: HPA finds the RNA at low tissue specificity; a medicine acting on the wild-type protein would expose normal tissue too. HPA PRKCI: RNA low tissue specificity; high antibody staining in 3 normal tissues; highest cancer staining ovarian cancer (4 of 12 high). Distribution: 2 cancer families in the corpus carry a prevalence row, label threshold or catalogue link for it (Leukaemia, Myeloid neoplasms); Open Targets associates it with 1 specific cancer type at or above 0.5 (acute myeloid leukemia).

Calcium- and diacylglycerol-independent serine/ threonine-protein kinase that plays a general protective role against apoptotic stimuli, 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. Is necessary for BCR-ABL oncogene-mediated resistance to apoptotic drug in leukaemia cells, protecting leukaemia cells against drug-induced apoptosis. In cultured neurons, prevents amyloid beta protein-induced apoptosis by interrupting cell death process at a very early step. In glioblastoma cells, 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. Can form a protein complex in non-small cell lung cancer (NSCLC) cells with PARD6A and ECT2 and regulate ECT2 oncogenic activity by phosphorylation, which in turn promotes transformed growth and invasion. In response to nerve growth factor (NGF), acts downstream of SRC to phosphorylate and activate IRAK1, allowing the subsequent activation of NF-kappa-B and neuronal cell survival. Location: Cytoplasm; Membrane; Endosome; Nucleus (UniProt). Locus 3q26.2 (HGNC).
RNA: low tissue specificity, detected in all normal tissues.
Medium: Adrenal gland, Appendix, Bronchus, Cerebral cortex, Colon, Duodenum, Endometrium, Gallbladder.
Medium only: breast cancer, carcinoid, cervical cancer, endometrial cancer.
