== Function ==
 +
[https://www.uniprot.org/uniprot/PPIA_MACMU PPIA_MACMU] Catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides (By similarity). Exerts a strong chemotactic effect on leukocytes partly through activation of one of its membrane receptors BSG/CD147, initiating a signaling cascade that culminates in MAPK/ERK activation (By similarity). Activates endothelial cells (ECs) in a proinflammatory manner by stimulating activation of NF-kappa-B and ERK, JNK and p38 MAP-kinases and by inducing expression of adhesion molecules including SELE and VCAM1 (By similarity). Induces apoptosis in ECs by promoting the FOXO1-dependent expression of CCL2 and BCL2L11 which are involved in EC chemotaxis and apoptosis (By similarity). In response to oxidative stress, initiates proapoptotic and antiapoptotic signaling in ECs via activation of NF-kappa-B and AKT1 and up-regulation of antiapoptotic protein BCL2 (By similarity). Negatively regulates MAP3K5/ASK1 kinase activity, autophosphorylation and oxidative stress-induced apoptosis mediated by MAP3K5/ASK1 (By similarity). Necessary for the assembly of TARDBP in heterogeneous nuclear ribonucleoprotein (hnRNP) complexes and regulates TARDBP binding to RNA UG repeats and TARDBP-dependent expression of HDAC6, ATG7 and VCP which are involved in clearance of protein aggregates (By similarity). Plays an important role in platelet activation and aggregation (By similarity). Regulates calcium mobilization and integrin ITGA2B:ITGB3 bidirectional signaling via increased ROS production as well as by facilitating the interaction between integrin and the cell cytoskeleton (By similarity). Binds heparan sulfate glycosaminoglycans (By similarity).[UniProtKB:P17742][UniProtKB:P62937]

TRIMCyps are primate antiretroviral proteins that potently inhibit HIV replication. Here we describe how rhesus macaque TRIMCyp (RhTC) has evolved to target and restrict HIV-2. We show that the ancestral cyclophilin A (CypA) domain of RhTC targets HIV-2 capsid with weak affinity, which is strongly increased in RhTC by two mutations (D66N and R69H) at the expense of HIV-1 binding. These mutations disrupt a constraining intramolecular interaction in CypA, triggering the complete restructuring (&gt;16 A) of an active site loop. This new configuration discriminates between divergent HIV-1 and HIV-2 loop conformations mediated by capsid residue 88. Viral sensitivity to RhTC restriction can be conferred or abolished by mutating position 88. Furthermore, position 88 determines the susceptibility of naturally occurring HIV-1 sequences to restriction. Our results reveal the complex molecular, structural and thermodynamic changes that underlie the ongoing evolutionary race between virus and host.
