Protein Structure
UniProt Annotation
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'. In case of infection with vesicular stomatitis virus (VSV), impairs viral replication. {ECO:0000269PubMed:11381086, ECO:0000269PubMed:12606582, ECO:0000269PubMed:12824288, ECO:0000269PubMed:16478986, ECO:0000269PubMed:17670836}.
