1 PKC activation induces the intracellular movement and co-localization of RACK1 and Src, and the tyrosine phosphorylation of RACK1. Tyrosine receptor for activated C kinase 1 Homo sapiens
2 Moreover, Src activity is necessary for both the tyrosine phosphorylation of RACK1 and the binding of RACK1 to Src"s SH2 domain that occur following PKC activation. Tyrosine receptor for activated C kinase 1 Homo sapiens
3 Moreover, Src activity is necessary for both the tyrosine phosphorylation of RACK1 and the binding of RACK1 to Src"s SH2 domain that occur following PKC activation. Tyrosine receptor for activated C kinase 1 Homo sapiens
4 To identify the tyrosine(s) on RACK1 that is phosphorylated by Src, we generated and tested a series of RACK1 mutants. Tyrosine receptor for activated C kinase 1 Homo sapiens
5 We found that Src phosphorylates RACK1 on Tyr 228 and/or Tyr 246, highly-conserved tyrosines located in the sixth WD repeat that interact with Src"s SH2 domain. Tyrosine receptor for activated C kinase 1 Homo sapiens
6 We found that Src phosphorylates RACK1 on Tyr 228 and/or Tyr 246, highly-conserved tyrosines located in the sixth WD repeat that interact with Src"s SH2 domain. Tyrosine receptor for activated C kinase 1 Homo sapiens
