CC -!- FUNCTION: Catalyzes the cis-trans isomerization of proline imidic
CC peptide bonds in oligopeptides (By similarity). Exerts a strong
CC chemotactic effect on leukocytes partly through activation of one of
CC its membrane receptors BSG/CD147, initiating a signaling cascade that
CC culminates in MAPK/ERK activation (By similarity). Activates
CC endothelial cells (ECs) in a proinflammatory manner by stimulating
CC activation of NF-kappa-B and ERK, JNK and p38 MAP-kinases and by
CC inducing expression of adhesion molecules including SELE and VCAM1 (By
CC similarity). Induces apoptosis in ECs by promoting the FOXO1-dependent
CC expression of CCL2 and BCL2L11 which are involved in EC chemotaxis and
CC apoptosis (By similarity). In response to oxidative stress, initiates
CC proapoptotic and antiapoptotic signaling in ECs via activation of NF-
CC kappa-B and AKT1 and up-regulation of antiapoptotic protein BCL2 (By
CC similarity). Negatively regulates MAP3K5/ASK1 kinase activity,
CC autophosphorylation and oxidative stress-induced apoptosis mediated by
CC MAP3K5/ASK1 (By similarity). Necessary for the assembly of TARDBP in
CC heterogeneous nuclear ribonucleoprotein (hnRNP) complexes and regulates
CC TARDBP binding to RNA UG repeats and TARDBP-dependent expression of
CC HDAC6, ATG7 and VCP which are involved in clearance of protein
CC aggregates (By similarity). Plays an important role in platelet
CC activation and aggregation (By similarity). Regulates calcium
CC mobilization and integrin ITGA2B:ITGB3 bidirectional signaling via
CC increased ROS production as well as by facilitating the interaction
CC between integrin and the cell cytoskeleton (By similarity). Binds
CC heparan sulfate glycosaminoglycans (By similarity).
CC {ECO:0000250|UniProtKB:P17742, ECO:0000250|UniProtKB:P62937}.
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 Evidence={ECO:0000250|UniProtKB:P62937};
CC -!- ACTIVITY REGULATION: Binds cyclosporin A (CsA). CsA mediates some of
CC its effects via an inhibitory action on PPIase.
CC {ECO:0000250|UniProtKB:P62937}.
CC -!- SUBUNIT: Interacts with protein phosphatase PPP3CA/calcineurin A (By
CC similarity). Interacts with isoform 2 of BSG/CD147 (By similarity).
CC Interacts with FOXO1; the interaction promotes FOXO1 dephosphorylation,
CC nuclear accumulation and transcriptional activity (By similarity).
CC Interacts with integrin ITGA2B:ITGB3; the interaction is ROS and
CC peptidyl-prolyl cis-trans isomerase (PPIase) activity-dependent and is
CC increased in the presence of thrombin (By similarity). Interacts with
CC MAP3K5 (By similarity). Interacts with TARDBP; the interaction is
CC dependent on the RNA-binding activity of TARDBP and the PPIase activity
CC of PPIA/CYPA and the acetylation of PPIA/CYPA at Lys-125 favors the
CC interaction (By similarity). Interacts with HNRNPA1, HNRNPA2B1, HNRNPC,
CC RBMX, HNRNPK and HNRNPM (By similarity). {ECO:0000250|UniProtKB:P17742,
CC ECO:0000250|UniProtKB:P62937}.
CC -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250|UniProtKB:P62937}.
CC Secreted {ECO:0000250|UniProtKB:P62937}. Nucleus
CC {ECO:0000250|UniProtKB:P62937}. Note=Secretion occurs in response to
CC oxidative stress in vascular smooth muscle through a vesicular
CC secretory pathway that involves actin remodeling and myosin II
CC activation, and mediates ERK1/2 activation.
CC {ECO:0000250|UniProtKB:P62937}.
CC -!- PTM: Acetylation at Lys-125 markedly inhibits catalysis of cis to trans
CC isomerization (By similarity). PPIA acetylation also antagonizes the
CC immunosuppressive effects of cyclosporine by inhibiting the sequential
CC steps of cyclosporine binding and calcineurin inhibition (By
CC similarity). Acetylation at Lys-125 favors the interaction with TARDBP
CC (By similarity). {ECO:0000250|UniProtKB:P62937}.
CC -!- SIMILARITY: Belongs to the cyclophilin-type PPIase family. PPIase A
CC subfamily. {ECO:0000305}.
