C14B9.2 encodes a protein disulfide isomerase; by homology, the product of C14B9.2 is predicted to function in oxidative protein folding in the endoplasmic reticulum (ER); C14B9.2 transcript levels are increased in response to ER stress.
Predicted to enable protein disulfide isomerase activity. Involved in IRE1-mediated unfolded protein response. Predicted to be located in cell surface and endoplasmic reticulum. Is an ortholog of human PDIA4 (protein disulfide isomerase family A member 4).
