CC   -!- FUNCTION: PPIases accelerate the folding of proteins. It catalyzes the
CC       cis-trans isomerization of proline imidic peptide bonds in
CC       oligopeptides. Acts as a regulatory subunit for PP2A-like phosphatases
CC       modulating their activity or substrate specificity, probably by
CC       inducing a conformational change in the catalytic subunit, a direct
CC       target of the PPIase. Can reactivate inactive phosphatase PP2A-
CC       phosphatase methylesterase complexes (PP2Ai) in presence of ATP and
CC       Mg(2+) by dissociating the inactive form from the complex (By
CC       similarity). {ECO:0000250}.
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 {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the PTPA-type PPIase family. {ECO:0000305}.
