PPP6C
PPP6C (Serine/threonine-protein phosphatase 6 catalytic subunit) is an enzyme. The public catalogues list it as an oncogene driver and a tumour suppressor, and it is called a cancer driver by mutation analysis of patient cohorts. Tied to Skin cancer, Melanoma and Basal cell carcinoma.
Overview
Catalytic subunit of protein phosphatase 6 (PP6). PP6 is a component of a signalling pathway regulating cell cycle progression in response to IL2 receptor stimulation. N-terminal domain restricts G1 to S phase progression in cancer cells, in part through control of cyclin D1.
Open Targets scores its association with cancer at 0.70 (direct and indirect evidence; datatypes literature 0.84, genetic association 0.00, somatic mutation 0.91). IntOGen calls it a driver in 5 cohorts (3 activating, 2 loss-of-function), covering Basal Cell Carcinoma, Melanoma, Cutaneous Melanoma.

Biology
Catalytic subunit of protein phosphatase 6 (PP6). PP6 is a component of a signalling pathway regulating cell cycle progression in response to IL2 receptor stimulation. N-terminal domain restricts G1 to S phase progression in cancer cells, in part through control of cyclin D1. During mitosis, regulates spindle positioning. Down-regulates MAP3K7 kinase activation of the IL1 signalling pathway by dephosphorylation of MAP3K7. Also participates in the innate immune defense against viruses by desphosphorylating RIGI, an essential step that triggers RIGI-mediated signalling activation. Location: Mitochondrion; Cytoplasm (UniProt). Locus 9q33.3 (HGNC).

Notes
top- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: IntOGen calls it an activating (Act) driver in 3 cohorts; IntOGen calls it a loss-of-function (LoF) driver in 2 cohorts. Evidence tier "cohort-driver" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
