DnaJ (Hsp40) homolog, subfamily B, member 9; dnaJ homolog subfamily B member 9; endoplasmic reticulum DNA J domain-containing protein 4; endoplasmic reticulum DnaJ homolog 4; ERdj4; ER-resident protein ERdj4; MDG1; MDG-1; microvascular endothelial differentiation gene 1 protein; MST049; MSTP049.

Co-chaperone for Hsp70 protein HSPA5/BiP that acts as a key repressor of the ERN1/IRE1-mediated unfolded protein response (UPR) (By similarity) . J domain-containing co-chaperones stimulate the ATPase activity of Hsp70 proteins and are required for efficient substrate recognition by Hsp70 proteins (PubMed:18400946) . In the unstressed endoplasmic reticulum, interacts with the luminal region of ERN1/IRE1 and selectively recruits HSPA5/BiP: HSPA5/BiP disrupts the dimerization of the active ERN1/IRE1 luminal region, thereby inactivating ERN1/IRE1 (By similarity) . Also involved in endoplasmic reticulum-associated degradation (ERAD) of misfolded proteins. Required for survival of B-cell progenitors and normal antibody production (By similarity) .
