FRS2 (FGFR substrate 2; also SNT and FSR2-alpha ) is a 70‑90 kDa member of the FSR family of lipid-anchored docking proteins. It is an intermediary between FGF and TRK receptors, and their Ras/MAPK signaling cascades. Human FRS2 is 512 amino acids (aa) in length. It 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 Tyr-rich region that serves as a docking site for Grb2 and Shp2 (aa 196‑471). One splice form shows a deletion of the C-terminal four amino acids. Over aa 121‑449, human FRS2 is 99% and 94% aa identical to dog and mouse FRS2, respectively.

Scientific Data Images for Human FRS2 Antibody
Detection of FRS2 in A172 Human Cell Line by Flow Cytometry.
A172 human glioblastoma cell line was stained with Mouse Anti-Human FRS2 Monoclonal Antibody (Catalog # MAB40691, filled histogram) or isotype control antibody (Catalog # MAB0041, open histogram), followed by Allophycocyanin-conjugated Anti-Mouse IgG F(ab')2Secondary Antibody (Catalog # F0101B). To facilitate intracellular staining, cells were fixed with paraformaldehyde and permeabilized with saponin.Applications for Human FRS2 Antibody
