Here we demonstrate that the T cell antigen receptor zeta - chain - associated ZAP - 70 kinase and T cell antigen receptor zeta - chain immunoreceptor tyrosine - based activation motifs are essential for the membrane recruitment of SOS and Vav .
 GENE: T cell antigen receptor zeta - chain - associated ZAP - 70 kinase; GENE: T cell antigen receptor zeta - chain immunoreceptor tyrosine - based activation motifs; GENE: SOS; GENE: Vav
