Biochemically we show that the stimulated tyrosine phosphorylation of Vav , Shc , and ZAP-70 itself is diminished, whereas that of Slp-76 is increased in cells reconstituted with Delta .
 ( protein: ZAP-70, None) , ( protein: Slp-76, None) , ( protein: Shc, None) , ( protein: Vav, None) , ( protein: Delta, None)
