    Cyclophilin (CyP) is a ubiquitious intracellular protein that binds the immunosuppressive drug cyclosporin A (CsA). CyP-CsA forms a ternary complex with calcineurin and thereby inhibits T-cell activation. CyP also has enzymatic activity, catalyzing the cis-trans isomerization of peptidyl-prolyl amide bonds.
