Abstract excerpt
The immunosuppressants FK506 and cyclosporin A (CsA) bound to their receptors, FKBP12 or cyclophilin, inhibit the Ca2+/calmodulin-dependent protein phosphatase, calcineurin, preventing T cell activation or, in yeast, recovery from alpha-mating factor arrest. Vegetative growth of yeast does not require calcineurin, and in strains sensitive to FK506 or CsA, growth is inhibited by concentrations of drug much higher...
