PPIL2, which belongs to the cyclophilin family of peptidylprolyl isomerases, is an enzyme that plays an important role in protein folding, immunosuppression by cyclosporin A, and infection of HIV-1 virions. This protein interacts with the proteinase inhibitor eglin c and is localized in the nucleus. Recombinant PPIL2 protein was expressed in E. coli. Source: Recombinant corresponding to aa1-527 of human PPIL2 6x His tagged expressed in E. coli.
