WebTo inhibit calcineurin and exert immunosuppressive effects, tacrolimus must bind to the 12-kDa FK506-binding protein (FKBP12), but it can also have calcineurin-independent effects. WebCsA and FKBP-FK506 (but not cyclophilin, FKBP, FKBP-rapamycin, or FKBP-506BD)competitively bind to and inhibit the Ca2+- and calmodulin-dependent phosphatase calcineurin, although the binding and inhibition of calcineurin do not require calmodulin.

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 ... WebMar 15, 2011 · Additional methods use (i) rapamycin (Rap), which binds FKBP (FK506 binding protein) and Frb [FKBP-Rap binding domain of mammalian target of Rap (mTOR)], or (ii) FK506, which binds FKBP and calcineurin, or cyclosporin A, to regulate cellular processes in response to the addition of either Rap or FK506, respectively. WebJul 12, 2002 · Calcineurin, a Ca2+/calmodulin-dependent protein phosphatase, is the common target for two immunophilin-immunosuppressant complexes, cyclophilin A-cyclosporin A (CyPA-CsA) and FKBP-FK506. How the two structurally distinct immunophilin-drug complexes bind the same target has remained unknown. cite my source for me
