Calcineurin is a common target of cyclophilin-cyclosporin A and FKBP-FK506 complexes

Abstract

Although the immediate receptors (immunophilins) of the immunosuppressants cyclosporin A (CsA) and FK506 are distinct, their similar mechanisms of inhibition of cell signaling suggest that their associated immunophilin complexes interact with a common target. We report here that the complexes cyclophilin-CsA and FKBP-FK506 (but not cyclophilin, FKBP, FKBP-rapamycin, or FKBP-506BD) competitively bind to and inhibit the Ca(2+)- and calmodulin-dependent phosphatase calcineurin, although the binding and inhibition of calcineurin do not require calmodulin. These results suggest that calcineurin is involved in a common step associated with T cell receptor and IgE receptor signaling pathways and that cyclophilin and FKBP mediate the actions of CsA and FK506, respectively, by forming drug-dependent complexes with and altering the activity of calcineurin-calmodulin.

  • These natural products remodeled their target proteins (immunophilins), recruiting novel interacting proteins to form entirely new ternary complexes.

    “their combined research revealed that these natural products remodeled their target proteins, a group of proteins named the immunophilins, recruiting novel interacting proteins to form entirely new ternary complexes (liu et al. 1991;Brown et al. 1994;Sabatini et al. 1994).”
  • Cyclosporin A forms a binary complex with cyclophilin that is able to bind and inhibit calcineurin.

    “Another example of an MG is Cyclosporin A, which forms a binary complex with cyclophilin able to bind and inhibit calcineurin.80,81”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
