Teaching an old dogma new tricks: twenty years of Shc adaptor signalling.

Indirect recruitment of the signalling adaptor Shc to the fibroblast growth factor receptor 2 (FGFR2).

The adaptor protein Shc (Src homology and collagen-containing protein) plays an important role in the activation of signalling pathways downstream of RTKs (receptor tyrosine kinases) regulating diverse cellular functions, such as differentiation, adhesion, migration and mitogenesis. Despite being phosphorylated downstream of members of the FGFR (fibroblast growth factor receptor) family, a dire...

Insights into the Shc Family of Adaptor Proteins

The Shc family of adaptor proteins is a group of proteins that lacks intrinsic enzymatic activity. Instead, Shc proteins possess various domains that allow them to recruit different signalling molecules. Shc proteins help to transduce an extracellular signal into an intracellular signal, which is then translated into a biological response. The Shc family of adaptor proteins share the same struc...

New Tricks for an Old Dogma: How Estradiol Mediates Masculinization and Defeminization of Sexual Behavior

The Shc adaptor protein is highly phosphorylated at conserved, twin tyrosine residues (Y239/240) that mediate protein–protein interactions

BACKGROUND Signal transduction initiated by a wide variety of extracellular signals involves the activation of protein-tyrosine kinases. Phosphorylated tyrosine residues in activated receptors or docking proteins then function as binding sites for the Src homology 2 (SH2) or phosphotyrosine-binding (PTB) domains of cytoplasmic signalling proteins. Shc is an adaptor protein that contains both PT...

A conserved amino-terminal Shc domain binds to phosphotyrosine motifs in activated receptors and phosphopeptides

BACKGROUND Signal transduction by growth factor receptor protein-tyrosine kinases is generally initiated by autophosphorylation on tyrosine residues following ligand binding. Phosphotyrosines within activated receptors form binding sites for the Src homology 2 (SH2) domains of cytoplasmic signalling proteins. One such protein, Shc, is tyrosine phosphorylated in response to a large number of gro...
