Specifically, hSpry2 inhibits the fibroblast growth factor receptor (FGFR)-induced mitogen-activated protein kinase pathway but conversely prolongs activity of the same pathway following epidermal growth factor (EGF) stimulation, where activated EGF receptors are retained on the cell surface. In this study it is demonstrated that hSpry2 is tyrosine-phosphorylated upon stimulation by either FGFR or EGF and subsequently binds endogenous c-Cbl with high affinity. A conserved motif on hSpry2, together with phosphorylation on tyrosine 55, is required for its enhanced interaction with the SH2-like domain of c-Cbl. A hSpry2 mutant (Y55F) that did not exhibit an enhanced binding with c-Cbl failed to retain EGF receptors on the cell surface. Furthermore, individually mutating hSpry2 residues 52-59 to alanine indicated a tight correlation between their affinity for c-Cbl binding and their inhibition of ERK2 activity in the FGFR pathway. We postulate that tyrosine phosphorylation "activates" hSpry2 by enhancing its interaction with c-Cbl and that this interaction is critical for its physiological function in a signal-specific context."xsd:string |
