1 In this study, we show that stimulation of C2C12 myoblasts with FGF-2 induces SHP-2 complex formation with tyrosyl-phosphorylated FGFR substrate 2 alpha (FRS-2 alpha). cyclo(tyrosyl-tyrosyl) protein tyrosine phosphatase non-receptor type 11 Homo sapiens
2 Both the catalytic activity and, to a much lesser extent, the Grb2 binding-tyrosyl phosphorylation sites of SHP-2 are required for maximal FGF-2-induced Erk activity and Elk-1 transactivation. cyclo(tyrosyl-tyrosyl) protein tyrosine phosphatase non-receptor type 11 Homo sapiens
3 The constitutively active mutant of SHP-2 induces hyper-tyrosyl phosphorylation of FRS-2 alpha but fails to stimulate or potentiate either FGF-2-induced Erk activation or Elk-1 transactivation. cyclo(tyrosyl-tyrosyl) protein tyrosine phosphatase non-receptor type 11 Homo sapiens
