Shc possesses SH2 and PTB domains and serves a scaffolding function in signaling for a variety of receptor tyrosine kinases.
Shc exists in p46, p52 and p66 isoforms, which are produced by using alternative translation initiation sites or a differentially spliced message (1–3).
In response to extracellular signals, the SH2 and PTB domains of Shc interact with the activated receptors, leading to phosphorylation of Shc on three different tyrosine residues: Tyr239, Tyr240 and Tyr317 (4–6).
GRB2/Sos binds to Shc phosphorylated at these sites, activating the Ras/Raf/MAPK pathway (4).
Both Shc expression and its tyrosine phosphorylation play an essential and nonredundant role in thymic T cell development (7).
