Tacrolimus bonds to an immunophilin, FK506 binding protein (FKBP).Tacrolimus - an overview | ScienceDirect TopicsTacrolimus binds to immunophilins known as FK506-binding proteins (FKBPs) (Fig. 35-4). The resulting tacrolimus-immunophilin complex produces the same action and effects as described for cyclosporine. Tacrolimus is approximately 100 times more potent than cyclosporine, however.

Immunosuppressants Used in Solid Organ Transplantation

Dec 22, 2006 · The mechanism of action of the two drugs is similar, as both bind to their own immunophilin molecule (cyclosporine to cyclophilin and tacrolimus to FK506-binding protein 12). The complex of the CNI with its respective binding protein inhibits activity of calcineurin--an enzyme necessary for the induction of T cell activation and proliferation.FK506 (Tacrolimus) | Calcineurin inhibitor | InvivoGenNov 25, 2016 · FK506 (Tacrolimus) is commonly used as an immunosuppressant to prevent the rejection of organ transplants. Similarly to cyclosporin A (CsA), FK506 blocks the activation of calcineurin through the formation of complexes with immunophilins. FK506 binds to a different immunophilin than CsA, called FK506 binding protein (FKBP) 12.Effects of FK506 and Cyclosporin A on Calcium Ionophore the mechanism of action of cyclosporin a and fk506The effect of FK506 on ionophore-induced mitochondrial depolarization was tested as a control since it also inhibits these phosphatases but does not inhibit the PTP (Connern and Halestrap, 1994).
