CC   -!- FUNCTION: PPIases accelerate the folding of proteins. It catalyzes the
CC       cis-trans isomerization of proline imidic peptide bonds in
CC       oligopeptides.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=[protein]-peptidylproline (omega=180) = [protein]-
CC         peptidylproline (omega=0); Xref=Rhea:RHEA:16237, Rhea:RHEA-
CC         COMP:10747, Rhea:RHEA-COMP:10748, ChEBI:CHEBI:83833,
CC         ChEBI:CHEBI:83834; EC=5.2.1.8;
CC   -!- SUBCELLULAR LOCATION: Cytoplasm.
CC   -!- MISCELLANEOUS: Binds to the immunosuppressant drug FK506.
CC   -!- SIMILARITY: Belongs to the FKBP-type PPIase family. FKBP1 subfamily.
CC       {ECO:0000305}.
CC   -!- SEQUENCE CAUTION:
CC       Sequence=EAA32060.2; Type=Erroneous initiation; Evidence={ECO:0000305};
