Tacrolimus (FK-506) is a drug that inhibits an enzyme called calcineurin. Calcineurin is a protein phosphatase. This is an enzyme that dephosphorylates (removes phosphate groups) from proteins. When added to cells, tacrolimus can inhibit the dephosphorylation of a protein called NFAT, but it cannot prevent the dephosphorylation of a protein called CDK1 . What is the most likely explanation for
this finding? A. Calcineurin requires an additional cofactor to dephosphorylate NFAT B. NFAT is a substrate of calcineurin, but CDK1 is not C. Tacrolimus is a competitive inhibitor of calcineurin for NFAT and CDK11 D. Tacrolimus changes the optimum pH for calcineurin
