Historically , Cyps were first identified by their ability to bind the immunosuppressive agent cyclosporin A ( CsA ) with high affinity ; they later were found to have peptidyl - prolyl cis - trans isomerase ( PPIase ) activity , which catalyzes the folding of oligopeptides at proline - peptide bonds in vitro and may be important for protein folding in vivo .
 GENE: Cyps; GENE: peptidyl - prolyl cis - trans isomerase; GENE: PPIase
