WebThe FK506–FKBP complex is wedged between the regulatory domain and the catalytic site and likely inhibits calcineurin by making it difficult for phosphoproteins to have access to the catalytic site. It is unclear whether FKBP and calcineurin interact physiologically via a natural ligand that functions like FK506 to facilitate their interaction. WebTo inhibit calcineurin and exert immunosuppressive effects, tacrolimus must bind to the 12-kDa FK506-binding protein (FKBP12), but it can also have calcineurin-independent effects.
