PIN1(redirected from PPIase Pin1)
PIN1A gene on chromosome 19p13 that encodes an essential peptidylprolyl isomerase, which regulates mitosis by interacting with NIMA and downregulating its mitosis-promoting activity. PIN1 downregulates BTK’s kinase activity, transactivates multiple oncogenes and induces centrosome amplification, chromosome instability and cell transformation. PIN1 is required for efficient dephosphorylation and recycling of RAF1 after mitogen activation.
