In previous studies, we identified calcineurin mutations that block binding by the cyclophilin A /CsA or FKBP12 /FK506 complexes and thereby render yeast cells resistant to the antifungal effects of CsA or FK506 .
 ( protein: calcineurin, None) , ( protein: calcineurin mutations, None) , ( protein: cyclophilin A, None) , ( protein: FKBP12, None)
