Calcineurin inhibitory compounds and anchoring protein to induce IL-2 gene expression

摘要

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.
