DNAJC10

Endoplasmic reticulum disulfide reductase that collaborates directly with the chaperone BIP/HSPA5 (GRP78) to maintain protein quality control by facilitating either the correct folding or the targeted degradation of misfolded proteins. Essential for efficient maturation of newly synthesized polypeptides in the endoplasmic reticulum, binds to substrate proteins and specifically catalyzes the reduction and removal of improper (non-native) disulfide bonds during the folding process. In endoplasmic reticulum-associated degradation (ERAD), DNAJC10 reduces incorrect disulfide bonds specifically in misfolded glycoproteins that have been recognized by EDEM1, a key component of the ERAD pathway, thereby enabling their retrotranslocation and degradation. Promotes apoptotic signaling pathway in response to endoplasmic reticulum stress..
