Structure
The phosphatase consists of 521 [3] aminoacids. The structure have been published 2013 by Qilu Ye et al. [4]. For their experiments they used x-ray diffraction. The PDB validation obtained a Resolutionof 3.0 Å, a free R-value of 0.273 and a work R-value of 0.241 [5].
The secondary structure includes mostly helical structures:

Binding Partners
The main partners of interaction are Calmodulin,
Calcineurin is inhibited by the immunosuppressive drugs tacrolismus (FK506) or cyclosporine A (CsA). CsA and FK506 conduct their therapeutic role thought binding to the immunophilins cyclophilin and FK506 binding protein (FK506BP) respectively. The complexes CsA-cyclophilin and FK506-FK506BP bind then to calcineurin in a calcium-dependent manner thus inhibiting its phosphatase activity. Therefore the addition of these drugs to lymphocyte T prevent NFAT translocation to the nucleus and the subsequent activation its target geneHo S1, Clipstone N, Timmermann L, Northrop J, Graef I, Fiorentino D, Nourse J, Crabtree GR (1996).
