HRP-1579 Recombinant Human PPIA Protein $300

Recombinant Human PPIA Protein

Product Name: Recombinant Human PPIA Protein
Catalog #:  HRP-1579
Manufacture:  LD Biopharma, Inc.

Human peptidyl-prolyl cis-trans isomerase A (PPIA) gene encodes 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. The encoded protein is a cyclosporin binding-protein and may play a role in cyclosporine A-mediated immunosuppression. The protein can also 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.

Full-length human PPIA (164aa, derived from BC073992) gene was constructed with 29 aa N-terminal T7 / His / TEV cleavage site Tag and expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
