General annotation (Comments)

Function	Probably plays a role in facilitating the assembly of multimeric protein complexes inside the ER By similarity.
Subunit structure	Interacts with DNAJC1 (via J domain) By similarity. 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 CABP1, DNAJB11, HSP90B1, HSPA5, HYOU, PDIA2, PDIA4, PPIB, SDF2L1, UGT1A1 and very small amounts of ERP29, but not, or at very low levels, CALR nor CANX. Interacts with TMEM132A and TRIM21. May form a complex with ERLEC1, OS9, SEL1L and SYVN1 By similarity. Interacts with MX1 By similarity.
Subcellular location	Endoplasmic reticulum lumen By similarity. Melanosome By similarity. Cytoplasm By similarity.
Sequence similarities	Belongs to the heat shock protein 70 family.
