Purity ~85% (SDS-PAGE). PIN4, also known as Peptidyl-prolyl cis-trans isomerase NIMA-interacting 4, is peptidyl-prolyl cis/trans isomerase (PPIase) that interacts with NIMA and is essential for cell cycle regulation. There are two different isoforms which are PAR14 and PAR17. PIN4/PAR17 was imported into mitochondria in a time and membrane potential-dependent manner, where it reached the mitochondrial matrix. Moreover, Pin4 protein was shown to bind to double-stranded DNA under physiological salt conditions. Source: Recombinant corresponding to aa1-156 from human PIN4, fused to His-tag at N-terminus expressed in E.coli.
