as indicated by western blotting with anti-phosphotyrosine-specific antibodies and confirmed by phosphoamino acid analysis , we now demonstrate that interaction of the t cell growth factor interleukin 2 ( il2 ) with its high affinity receptor on il2-sensitive human peripheral blood lymphoblasts induces tyrosine phosphorylation of proteins of 92 , 80 , 78 , 70-75 , and 57 kda .
