Rabbit anti-Human PPP1R15A Polyclonal Antibody

Uniprot Id

O75807

Target Species

Human

Target Name

PPP1R15A

Target Full Name

Protein phosphatase 1 regulatory subunit 15A

Target Function

Recruits the serine/threonine-protein phosphatase PP1 to dephosphorylate the translation initiation factor eIF-2A/EIF2S1, thereby reversing the shut-off of protein synthesis initiated by stress-inducible kinases and facilitating recovery of cells from stress. Down-regulates the TGF-beta signaling pathway by promoting dephosphorylation of TGFB1 by PP1. May promote apoptosis by inducing TP53 phosphorylation on 'Ser-15'.

Target Subcellular Location

Endoplasmic reticulum membrane; Peripheral membrane protein; Cytoplasmic side. Mitochondrion outer membrane; Peripheral membrane protein; Cytoplasmic side.

Target Protein Families

PPP1R15 family

Target Research Area

Epigenetics and Nuclear Signaling

Target Synonyms

Apoptosis associated protein; GADD 34; Growth arrest and DNA damage inducible 34; Growth arrest and DNA damage-inducible protein GADD34; Myeloid differentiation primary response protein MyD116 homolog; Ppp1r15a; PR15A_HUMAN; Protein phosphatase 1 regulatory (inhibitor) subunit 15A; Protein phosphatase 1 regulatory subunit 15A

Target Background

This gene is a member of a group of genes whose transcript levels are increased following stressful growth arrest conditions and treatment with DNA-damaging agents. The induction of this gene by ionizing radiation occurs in certain cell lines regardless of p53 status, and its protein response is correlated with apoptosis following ionizing radiation.
