Endoplasmic reticulum protein 29 (ERp29) is a chaperone protein that in humans is encoded by the ERP29gene.[5]
Function
ERp29 is a reticuloplasmin, a protein which resides in the lumen of the endoplasmic reticulum (ER). The protein shows sequence similarity to the protein disulfide-isomerase family.[6] However, it lacks the thioredoxin motif characteristic of this family, suggesting that this protein does not function as a disulfide isomerase.[6] The protein dimerizes and is thought to play a role in the processing of secretory proteins within the ER. Alternative splicing results in multiple transcript variants encoding different isoforms.[5]
