FRS2 (FGF R substrate 2; also known as SNT and FRS2-alpha ) is a 70‑90 kDa member of the FRS family of lipid-anchored docking proteins. It is an intermediary between FGF and RTK receptors and their Ras/MAPK signaling cascades. FRS2 contains a membrane-anchoring myristoylation signal (aa 1‑6), a PTB domain that interacts with FGF and NGF receptors (aa 13‑115), and a C-terminal tyrosine-rich region that serves as a docking site for GRB-2 and SHP-2 (aa 196‑471). Phosphorylation of Y436 by activated RTKs is required for efficient SHP-2 recruitment.
