General annotation (Comments)

Function

Molecular chaperone that functions in the processing and transport of secreted proteins. When associated with CNPY3, required for proper folding of Toll-like receptors. Functions in endoplasmic reticulum associated degradation (ERAD). Has ATPase activity By similarity. Ref.10

Subunit structure

Homodimer; disulfide-linked. 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 OS9 By similarity. Interacts with AIMP1; regulates its retention in the endoplasmic reticulum. Interacts with CNPY3; this interaction is disrupted in the presence of ATP. Interacts with TLR4, TLR9 and TLR11, but not with TLR3. Interacts with MZB1 in a calcium-dependent manner. Ref.6 Ref.8 Ref.9 Ref.10 Ref.12

Subcellular location

Endoplasmic reticulum lumen. Melanosome By similarity Ref.10.

Sequence similarities

Belongs to the heat shock protein 90 family.
