Protein Information (annotations from UniProt)

Database IDHIV0004750
UniProt IDP30040
Primary gene name(s)ERP29
Synonym gene name(s)C12orf8, ERP28
Protein nameEndoplasmic reticulum resident protein 29
Protein functionDoes not seem to be a disulfide isomerase. Plays an important role in the processing of secretory proteins within the endoplasmic reticulum, ER, possibly by participating in the folding of proteins in the ER.
Subcellular locationEndoplasmic reticulum lumen. Melanosome. Note=Identified by mass spectrometry in melanosome fractions from stage I to stage IV.
