PPP2R1A
PPP2R1A is a gene that drives cell growth when it is altered. The public catalogues list it as a drug target, an oncogene driver, a tumour suppressor and a biomarker, and clinical evidence ties its variants to diagnosis, prognosis or drug response. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Biology
The PR65 subunit of protein phosphatase 2A serves as a scaffolding molecule to coordinate the assembly of the catalytic subunit and a variable regulatory B subunit. Upon interaction with GNA12 promotes dephosphorylation of microtubule associated protein TAU/MAPT. Required for proper chromosome segregation and for centromeric localisation of SGO1 in mitosis. Together with RACK1 adapter, mediates dephosphorylation of AKT1 at 'Ser-473', preventing AKT1 activation and AKT-mTOR signalling pathway. Dephosphorylation of AKT1 is essential for regulatory T-cells (Treg) homeostasis and stability. Part of the striatin-interacting phosphatase and kinase (STRIPAK) complexes. Location: Cytoplasm; Nucleus; Chromosome; Chromosome, centromere (UniProt). Locus 19q13.41 (HGNC).
