Human Recombinant Cyclophilin B | 6310

Cyclophilin B is a cyclosporine-binding protein. It is both secreted and retained in the ER. When secreted, Cyclophilin B mediates chemotaxis and T cell adhesion to fibronectin. This is likely due to its prolyl cis/trans isomerase activity. Intracellularly, Cyclophilin B appears to serve as a molecular chaperone for molecules destined for secretion. It does so via stabilization, and facilitating the activity of additional chaperones. It also bind to cells derived from T- and B-lymphocytes, and may regulate cyclosporine A-mediated immunosuppression.
