WebThe FK506–FKBP complex is wedged between the regulatory domain and the catalytic site and likely inhibits calcineurin by making it difficult for phosphoproteins to have access to the catalytic site. It is unclear whether FKBP and calcineurin interact physiologically via a natural ligand that functions like FK506 to facilitate their interaction. WebCalcineurin’s activity requires association of its catalytic (A) subunit with an intrinsic regulatory (B) subunit. We hypothesized that calcineurin-sensitive signalling events should be affected by the depletion of calcineurin B subunits, thereby reducing the number of active A:B complexes. We therefore transfected rat basophilic leukemia ...
