Protein Information (annotations from UniProt)

Database IDHIV0004574
UniProt IDQ13217
Primary gene name(s)DNAJC3
Synonym gene name(s)P58IPK, PRKRI
Protein nameDnaJ homolog subfamily C member 3
Protein functionInvolved in the unfolded protein response, UPR during endoplasmic reticulum, ER stress. Acts as a negative regulator of the EIF2AK4/GCN2 kinase activity by preventing the phosphorylation of eIF-2-alpha at 'Ser-52' and hence attenuating general protein synthesis under ER stress, hypothermic and amino acid starving stress conditions, By similarity. Co-chaperone of HSPA8/HSC70, it stimulates its ATPase activity. May inhibit both the autophosphorylation of EIF2AK2/PKR and the ability of EIF2AK2 to catalyze phosphorylation of the EIF2A. May inhibit EIF2AK3/PERK activity. {ECO:0000250|UniProtKB:Q27968, ECO:0000250|UniProtKB:Q91YW3, ECO:0000269|PubMed:12601012, ECO:0000269|PubMed:8576172, ECO:0000269|PubMed:9447982, ECO:0000269|PubMed:9920933}.
