Protein

Serine/threonine-protein phosphatase 6 catalytic subunit

Gene

Organism

Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalytic subunit of protein phosphatase 6 (PP6). PP6 is a component of a signaling 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. Downregulates MAP3K7 kinase activation of the IL1 signaling pathway by dephosphorylation of MAP3K7. Participates also in the innate immune defense against viruses by desphosphorylating RIG-I/DDX58, an essential step that triggers RIG-I/DDX58-mediated signaling activation.5 Publications

Catalytic activityi

[a protein]-serine/threonine phosphate + H2O = [a protein]-serine/threonine + phosphate.

Interactioni

Subunit structurei

Protein phosphatase 6 (PP6) holoenzyme is proposed to be a heterotrimeric complex formed by the catalytic subunit, a SAPS domain-containing subunit (PP6R) and an ankyrin repeat-domain containing regulatory subunit (ARS). Interacts with IGBP1, MAP3K7, NFKBIE, PPP6R1, PPP6R2 and PPP6R3. Interacts with TRIM14 and WRNIP1; these interactions positively regulate the RIG-I/DDX58 signaling pathway (PubMed:29053956).5 Publications
