Calmodulin-dependent protein kinase IV regulates nuclear export of Cabin1 during T-cell activation

Pan, Fan, Means, Anthony R, Liu, Jun O

Calcium signaling is critical for activation of T lymphocytes and has been proposed to be transduced through multiple calmodulin target proteins. Whereas the calcineurin–NFAT signaling module is...
