Function

PIN1_HUMAN Essential PPIase that regulates mitosis presumably by interacting with NIMA and attenuating its mitosis-promoting activity. Displays a preference for an acidic residue N-terminal to the isomerized proline bond. Catalyzes pSer/Thr-Pro cis/trans isomerizations. Down-regulates kinase activity of BTK. Can transactivate multiple oncogenes and induce centrosome amplification, chromosome instability and cell transformation. Required for the efficient dephosphorylation and recycling of RAF1 after mitogen activation.^[1] ^[2] ^[3]

Publication Abstract from PubMed

The unique proline isomerase peptidyl-prolyl isomerase NIMA-interacting-1 (Pin1) is reported to activate numerous cancer-driving pathways simultaneously, and aberrant Pin1 activation is present in many human cancers. Here, we identified a novel hit compound, ZL-Pin01, that covalently modified Pin1 at Cys113 with an half-maximal inhibitory concentration (IC50) of 1.33 +/- 0.07 muM through screening an in-house library. Crystallographic study drove the process of structure-guided optimization and led to the potent inhibitor ZL-Pin13 with an IC50 of 0.067 +/- 0.03 muM. We obtained four co-crystal structures of Pin1 complexed with inhibitors that elucidated the detailed binding mode of the derivatives with Pin1. Interestingly, the co-crystal of Pin1 with ZL-Pin13 obtained by co-crystallization revealed the conformational change of Gln129 induced by the inhibitor. Furthermore, ZL-Pin13 effectively inhibited the proliferation and downregulated the Pin1 substrates in MDA-MB-231 cells. Collectively, we developed a potent covalent inhibitor of Pin1, ZL-Pin13, which could be an effective probe for studying the functional roles of Pin1.
