1 Inhibition of the protein phosphatase calcineurin (CaN), which has been implicated in the FK506-mediated blockade of T cell proliferation, was shown to involve a gain of function in the FKBP12/FK506 complex. Tacrolimus FKBP prolyl isomerase 1A pseudogene 4 Homo sapiens
2 The different capacities of FK506/FKBP complexes to affect CaN activity are partially caused by substitutions corresponding to the amino acid side chains K34 and I90 of FKBP12. Tacrolimus FKBP prolyl isomerase 1A pseudogene 4 Homo sapiens
3 Only the FK506 complexes of FKBP12, FKBP12.6, and FKBP51 showed high affinity to CaN; small interfering RNA against these FKBP allowed defining the contribution of individual FKBP in an NFAT reporter gene assay. Tacrolimus FKBP prolyl isomerase 1A pseudogene 4 Homo sapiens
