PPP5C

protein phosphatase 5 catalytic subunit

NCBI Gene: 5536 Ensembl GeneCards UniProt: P53041

Pathway candidate — not linked to PFS or PSSD by any record here

PPP5C is in the library because it belongs to the receptor chaperones family. No study, report or commentary in the corpus names it, so a variant in PPP5C is not, by itself, evidence of anything related to post-drug syndromes.

Gene summary

A protein-coding gene on chromosome 19 (steroid receptor chaperones). Encodes a serine/threonine phosphatase which is a member of the protein phosphatase catalytic subunit family. Proteins in this family participate in pathways regulated by reversible phosphorylation at serine and threonine residues; many of these pathways are involved in the regulation of cell growth and differentiation.

Protein reference (UniProt)

Protein: Serine/threonine-protein phosphatase 5
Function (excerpt): Serine/threonine-protein phosphatase that dephosphorylates a myriad of proteins involved in different signaling pathways including the kinases CSNK1E, ASK1/MAP3K5, PRKDC and RAF1, the nuclear receptors NR3C1, PPARG, ESR1 and ESR2, SMAD proteins and TAU/MAPT. Implicated in wide ranging cellular processes, including apoptosis, differentiation, DNA damage response, cell survival, regulation of ion channels or circadian rhythms, in response to steroid and thyroid hormones, calcium, fatty acids, TGF-beta as well as oxidative and genotoxic stresses. Participates in the control of DNA damage response mechanisms such as checkpoint activation and DNA damage repair through, for instance, the regulation ATM/ATR-signaling and dephosphorylation of PRKDC and TP53BP1. Inhibits ASK1/MAP3K5-mediated apoptosis induced by oxidative stress. Plays a positive role in adipogenesis, mainly through the dephosphorylation and activation of PPARG transactivation function (By similarity).
Subcellular location: Nucleus; Cytoplasm; Cell membrane.
Tissue specificity: Ubiquitous.

Why its pathway is in the library

Chaperone/co-chaperone control of steroid-receptor folding and sensitivity is a regulatory layer above the receptors themselves, tied to stress-axis signaling.

Written for the whole receptor chaperones family, not for PPP5C specifically.

Mentioned in 0 corpus records

No corpus record names PPP5C directly yet. It is in the library because it sits in a pathway the corpus tracks (Receptor chaperones).
