Purity: > 90% by SDS-PAGE Format: Liquid. In 20mM Tris buffer(pH 8.0) containing 10% glycerol, 1mM DTT.. FKBP2 is peptidyl proline isomerase enzyme and a member of the immunophilin protein family. This protein is predominantly expressed in thymus and T cells and plays a role in immunoregulation and basic cellular processes involving protein folding and trafficking. It is a cis-trans prolyl isomerase that binds the immunosuppressants FK506 and rapamycin. FKBP2 is thought to function as an ER chaperone and may also act as a component of membrane cytoskeletal scaffolds. Recombinant FKBP2 protein was expressed in E.coli and purified by using conventional chromatography techniques.
