PPIL3Peptidyl-prolyl cis-trans isomerase-like 3 is an enzyme that in humans is encoded by the PPIL3 gene.FunctionThis gene encodes a member of the cyclophilin family. Cyclophilins catalyze the cis-trans isomerization of peptidylprolyl imide bonds in oligopeptides. They have been proposed to act either as catalysts or as molecular chaperones in protein-folding events. Transcript variants derived from alternative splicing and/or alternative polyadenylation exist; some of these variants encode different isoforms.
