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.
Molecular Weight:~18.8kD (176aa), confirmed by MALDI-TOF
Enzyme Activity:Specific activity is > 700 nmol/min/mg, and is defined as the amount of enzyme that cleaves 1nmole of suc-AAFP-PNA per minute at 37°C in Tris-HCl pH 8.0 using chymotrypsin.
