Abstract:Pin1 is a peptidyl-prolyl isomerase (PPIase) that plays a central role in eukaryotic cell cycle regulation, making this protein an interesting target for cancer therapy. Pin1 exhibits high specificity for substrates where proline is preceded by phosphoserine or phosphothreonine. The protein comprises an N-terminal WW (tryptophan–tryptophan) domain and a C-terminal PPIase domain. The cyclic peptide [CRYPEVEIC] (square brackets are used to denote the cyclic structure) represents a lead compound for a new class o… Show more
