BIP, MIF2, GRP78, HEL-S-89n, 78 kDa glucose-regulated protein, GRP-78, Endoplasmic reticulum lumenal Ca(2+)-binding protein grp78, Heat shock 7 kDa protein 5, Immunoglobulin heavy chain-binding protein, HSPA5
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 DNAJC1, probably to facilitate the release of DNAJC1 from its substrate.
