Peptidyl-prolyl cis-trans isomerase B is an enzyme that in humans is encoded by the PPIB gene.The protein encoded by this gene is a cyclosporine-binding protein and is mainly located within the endoplasmic reticulum. It is associated with the secretory pathway and released in biological fluids. This protein can bind to cells derived from T- and B-lymphocytes and may regulate cyclosporine A-mediated immunosuppression.
