Peptidylprolyl isomerase A (cyclophilin A) Adenovirus (Ad-Cyclophilin A)

The protein encoded by this gene is a member of the peptidyl-prolyl cis-trans isomerase (PPIase) family. PPIases catalyze the cis-trans isomerization of proline imidic peptide bonds in oligopeptides and accelerate the folding of proteins. This protein is a cyclosporin binding-protein. It may play a role in cyclosporin A-mediated immunosuppression. This protein can interact with several HIV proteins including p55 gag, Vpr, and capsid protein. It has been shown to be necessary for the formation of infectious HIV virions.
