General annotation (Comments)

Function

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.

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 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. Interacts with TMEM132A and TRIM21. May form a complex with ERLEC1, OS9, SEL1L and SYVN1 By similarity. Interacts with MX1. Interacts with METTL23 and DNAJC10. Interacts with CEMIP; the interaction induces calcium leakage from the endoplamic reticulum and cell migration By similarity.

Subcellular location

Endoplasmic reticulum lumen By similarity. Melanosome By similarity. Cytoplasm By similarity.

Tissue specificity

Detected in the acrosome and principal piece of the caput epididymal spermatazoa, not detected in the cauda epididymal spermatazoa (at protein level). Ref.2

Sequence similarities

Belongs to the heat shock protein 70 family.
