Interestingly, we find that in contrast to SLP-76 , overexpression of SLAP-130 diminishes T cell antigen receptor -induced activation of the interleukin-2 promoter in Jurkat T cells and interferes with the augmentation of interleukin-2 promoter activity seen when SLP-76 is overexpressed in these cells.
