ABSTRACT:
The present invention provides compositions and methods useful for isolating calcineurin as well as inhibiting calcineurin activity. The compositions are peptides that contain regions that are homologous to calcineurin-binding regions of AKAP 79. Also provided are methods for determining if a cell contains a calcineurin-binding and PKA-binding anchoring protein that are useful for identifying additional proteins that bind both calcineurin and PKA. Another aspect of the present invention is methods for enhancing expression of interleukin 2 by T cells. Further provided are methods to identify proteins which interact with AKAP 79, and methods to identify inhibitors of AKAP 79 interaction with other proteins.
