Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 is an enzyme that in humans is encoded by the PIN1 gene. (Not to be confused with PIN1 (Pin-formed 1) an auxin transporter in Arabidopsis thaliana.)Pin 1 or peptidyl-prolyl cis/trans isomerase (PPIase) isomerizes only phospho-Serine/Threonine-Proline motifs. The enzyme binds to a subset of proteins and thus plays a role as a post phosphorylation control in regulating protein function.
