摘要: We have identified in the plasma membrane of chicken erythrocyte a 60-kDa tyrosine-specific protein kinase immunologically related to transforming pp60v-src Rous sarcoma virus. The phosphorylated heavy chains tumor-bearing rabbit (TBR) antibodies reactive with pp60c-src at tyrosine immune complex assays. was as by [35S]methionine labeling erythrocytes and autophosphorylation complexes. migrated on two-dimensional gel electrophoresis an apparent pI molecular mass similar pp60c-src. A membrane-enriched fraction isolated from red cells contained majority activity. solubilized detergents 0.5% (wt/vol) Na-deoxycholate 1% (vol/vol) Nonidet P-40. One molar NaCl much less effective, indicating strong association membrane. Incubation [32P]ATP resulted phosphorylation anion transport band 3. Band 3 blocked TBR antibodies, that recognized responsible for phosphorylation. These results demonstrate avian contains tightly bound identical or closely this is vitro.
