Virol. 81:11106-11115(2007). CC -!- FUNCTION: Recruits the serine/threonine-protein phosphatase PP1 to CC dephosphorylate the translation initiation factor eIF-2A/EIF2S1, CC thereby reversing the shut-off of protein synthesis initiated by CC stress-inducible kinases and facilitating recovery of cells from CC stress. Down-regulates the TGF-beta signaling pathway by promoting CC dephosphorylation of TGFB1 by PP1. May promote apoptosis by inducing CC TP53 phosphorylation on 'Ser-15'. In case of infection with vesicular CC stomatitis virus (VSV), impairs viral replication.

CC Mitochondrion outer membrane; Peripheral membrane protein; Cytoplasmic CC side {ECO:0000250|UniProtKB:O75807}. Note=Associates with membranes via CC an N-terminal amphipathic intramembrane region. CC {ECO:0000250|UniProtKB:O75807}.

CC {ECO:0000269|PubMed:12824288}. CC -!- DEVELOPMENTAL STAGE: Expression starts at 8.5 dpc, and decreases to CC undetectable levels at 10.5 dpc and 11.5 dpc. Expression is strongly CC up-regulated at 12.5 dpc, decreases at 16.5 dpc and reappears at 18.5 CC dpc. At 12.5 dpc, ubiquitously expressed, with high levels in brain, CC spinal cord, tongue, lung and genital tubercle. CC {ECO:0000269|PubMed:12824288}. CC -!- INDUCTION: By IL6 and various endoplasmic stresses such as methyl CC methanesulfonate. By infection with various viruses such as vesicular CC stomatitis virus (VSV). {ECO:0000269|PubMed:12606582, CC ECO:0000269|PubMed:12824288, ECO:0000269|PubMed:17670836, CC ECO:0000269|PubMed:8139541}. CC -!- PTM: Phosphorylated at multiple Ser/Thr residues. Phosphorylated on CC tyrosine by LYN; which impairs its antiproliferative activity. CC Phosphorylation at Tyr-239 enhances proteasomal degradation, this CC position is dephosphorylated by PTPN2. {ECO:0000250|UniProtKB:O75807}. CC -!- PTM: Polyubiquitinated. Exhibits a rapid proteasomal degradation with a CC half-life under 1 hour, ubiquitination depends on endoplasmic reticulum CC association. {ECO:0000250|UniProtKB:O75807}. CC -!- DISRUPTION PHENOTYPE: Mice display abnormal erythrocytes and reduced CC hemoglobin content due to defects in hemoglobin synthesis. CC {ECO:0000269|PubMed:12824288, ECO:0000269|PubMed:16478986}. CC -!- SIMILARITY: Belongs to the PPP1R15 family. {ECO:0000305}.
