Abstract:
Cyclophilins together with FK-506-binding proteins and parvulins, belong to a group of proteins that have peptidyl-prolyl cis-trans isomerase activity. They also belong to proteins that are collectively known as immunophilins. Cyclophilins are found in all cells of all organisms studied, in both prokaryotes and eukaryotes. The first member of the cyclophilins to be identified in mammals, cyclophilin A, is the major cellular target for the immunosuppressive drug cyclosporin A. This review discusses recently available data about proteins with cyclophilin domain (CBD). Recent studies have implicated a diverse array of additional cellular functions for cyclophilins, including roles as chaperones and in cell signalling as well as in several human diseases.
