Status
Functioni
Probably plays a role in facilitating the assembly of multimeric protein complexes inside the endoplasmic reticulum. Involved in the correct folding of proteins and degradation of misfolded proteins via its interaction with DNAJC10, probably to facilitate the release of DNAJC10 from its substrate (By similarity).By similarity

Interactioni
Subunit structurei
Interacts with DNAJC1 (via J domain). Component of an EIF2 complex at least composed of CELF1/CUGBP1, CALR, CALR3, EIF2S1, EIF2S2, HSP90B1 and HSPA5. Part of a large chaperone multiprotein complex comprising DNAJB11, HSP90B1, HSPA5, HYOU, PDIA2, PDIA4, PDIA6, PPIB, SDF2L1, UGT1A1 and very small amounts of ERP29, but not, or at very low levels, CALR nor CANX (PubMed:12475965). Interacts with TMEM132A and TRIM21 (PubMed:12514190). May form a complex with ERLEC1, OS9, SEL1L and SYVN1. Interacts with DNAJC10. Interacts with MX1. Interacts with METTL23. Interacts with CEMIP; the interaction induces calcium leakage from the endoplasmic reticulum and cell migration. Interacts with PCSK4 form; the interaction takes place in the endoplasmic reticulum. Interacts with CIPC. Interacts with CCDC88B (via C-terminus); the interaction opposes ERN1-mediated JNK activation, protecting against apoptosis.By similarity2 Publications
