1 The PPIase activity of FKBP25 was far more sensitive to inhibition by rapamycin (IC50 = 50 nM) than FK506 (IC50 = 400 nM). Tacrolimus FKBP prolyl isomerase 3 Homo sapiens
2 PPIase activity of 100 nM FKBP25 was almost completely inhibited by 150 nM rapamycin while only 90% inhibition was achieved by 4 microM FK506. Tacrolimus FKBP prolyl isomerase 3 Homo sapiens
3 These data demonstrate that FKBP25 has a higher affinity for rapamycin than for FK506 and suggest that this cellular receptor may be an important target molecule for immunosuppression by rapamycin. Tacrolimus FKBP prolyl isomerase 3 Homo sapiens
