Background

Peptidyl-prolyl cis-trans isomerase A; also known as PPIase A; Rotamase A; Cyclophilin A; Cyclosporin A-binding protein; PPIA and CYPA; is a cytoplasm protein which belongs to thecyclophilin-type PPIase family and PPIase A subfamily. Cyclophilins (CyPs) are a family of proteins found in organisms ranging from prokaryotes to humans. These molecules exhibit peptidyl-prolyl isomerase activity; suggesting that they influence the conformation of proteins in cells. PPIA / Cyclophilin A accelerate the folding of proteins. It catalyzes the cis-trans isomerization of proline imidic peptide bonds in oligopeptides. PPIA / Cyclophilin A is secreted by vascular smooth muscle cells in response to inflammatory stimuli; and could thus contribute to atherosclerosis. It is not essential for mammalian cell viability. PPIA / Cyclophilin A can interact with several HIV proteins; including p55 gag; Vpr; and capsid protein; and has been shown to be necessary for the formation of infectious HIV virions.
