Our data are most consistent with a model in which recruitment to the TCR allows ZAP-70 autophosphorylation and binding to p56(lck) , which in turn phosphorylates Tyr-492 and/or Tyr-493 with consequent up-regulation of the ZAP-70 kinase activity .
 ( protein: ZAP-70, None) , ( protein: p56(lck), None) , ( protein: ZAP-70, None) , ( protein: TCR, None)
