CC   -!- FUNCTION: PPIases accelerate the folding of proteins. It catalyzes the
CC       cis-trans isomerization of proline imidic peptide bonds in
CC       oligopeptides. {ECO:0000269|PubMed:10669849}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[protein]-peptidylproline (omega=180) = [protein]-
CC         peptidylproline (omega=0); Xref=Rhea:RHEA:16237, Rhea:RHEA-

CC         ChEBI:CHEBI:83834; EC=5.2.1.8;
CC   -!- ACTIVITY REGULATION: Binds cyclosporin A (CsA). CsA mediates some of
CC       its effects via an inhibitory action on PPIase. Do not bind FK506.
CC       {ECO:0000269|PubMed:10669849}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm.
CC   -!- ALLERGEN: Causes an allergic reaction in human.
CC   -!- SIMILARITY: Belongs to the cyclophilin-type PPIase family.
CC       {ECO:0000305}.
