Protein Disulfide-Isomerase A3

**Semantic type:** Amino Acid, Peptide, or Protein|Enzyme

**Definition:** Protein disulfide-isomerase A3 (505 aa, ~57 kDa) is encoded by the human PDIA3 gene. This protein is involved in both the activity of the MHC class I peptide-loading complex and post-translational disulfide bond formation.
