Grb-2 specifically co-operates with Vav-1 in the up-regulation of NFAT/AP-1 transcription. CD28 costimulation resulted in a prolonged and sustained phosphorylation and membrane localization of Vav1 in comparison to T-cell receptor activation alone. Tyrosine-phosphorylated Vav1 is an early point of integration between the signaling routes triggered by the T-cell receptor and CD28.<br>Vav1 transduces TCR and co-stimulatory signals to multiple biochemical pathways and several cytoskeleton-dependent processes. The products of Vav1 activation, Rac1 and Cdc42, in turn activate the mitogen-activated protein kinases JNK and p38. Vav1 is also required for TCR-induced calcium flux, activation of the ERK MAP kinase pathway, activation of the NF-kB transcription factor, inside-out activation of the integrin LFA-1, TCR clustering, and polarisation of the T cell.
