Ppid, also known as Peptidyl-prolyl cis-trans isomerase D, is a member of peptidyl-propyl cis-trans isomerase (Pplase) family, which catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides and accelerates the folding of proteins. This protein can bind to the immunosuppressant cyclosporine A and was known that its overexpression the apoptosis in cancer cells.
