Targeting carcinogenesis: A role for the prolyl isomerase Pin1?

Abstract excerpt

Phosphorylation of proteins on serine or threonine residues that immediately precede proline (pSer/Thr-Pro) is a central signaling mechanism in cell proliferation and transformation. Recent studies indicate that certain pSer/Thr-Pro motifs in native proteins exist in two completely distinct conformations, cis and trans, whose conversion is markedly slowed down upon phosphorylation, but specifically catalyzed by...
