Overexpression of wild-type Grf40 in Jurkat cells induced a significant increase of SLP-76 -dependent interleukin (IL)-2 promoter and nuclear factor of activated T cell ( NF-AT ) activation upon T cell receptor ( TCR ) stimulation , whereas the COOH-terminal SH3-deleted Grf40 mutant lacked any recognizable increase in IL-2 promoter activity .
