Sci. Technol. 39:6313-6320(2005). 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 -!- ACTIVITY REGULATION: Binds cyclosporin A (CsA). CsA mediates some of CC its effects via an inhibitory action on PPIase (By similarity). CC {ECO:0000250}. CC -!- SUBCELLULAR LOCATION: Mitochondrion {ECO:0000305}. CC -!- ALTERNATIVE PRODUCTS: CC Event=Alternative splicing; Named isoforms=2; CC Name=1; CC IsoId=Q94A16-1; Sequence=Displayed; CC Name=2; CC IsoId=Q94A16-2; Sequence=VSP_055389; CC -!- TISSUE SPECIFICITY: Ubiquitous, mostly in aerial organs. CC {ECO:0000269|PubMed:15047905, ECO:0000269|PubMed:15051864}. CC -!- INDUCTION: Repressed by the munition hexahydro-1,3,5-trinitro-1,3,5- CC triazine, also known as Royal Demolition eXplosive (RDX). CC {ECO:0000269|PubMed:16173598}. CC -!- SIMILARITY: Belongs to the cyclophilin-type PPIase family. CC {ECO:0000305}.
