FRS2 (pY436) Antibody

Background

Fibroblast growth factor receptor substrate 2 (FRS2) is an intracellular adaptor protein that plays a pivotal role in the signaling pathways of fibroblast growth factor receptors (FGFRs). Upon FGFR activation, FRS2 becomes tyrosine-phosphorylated and acts as a docking platform for various signaling molecules. It primarily facilitates the recruitment of Grb2 and Sos, leading to the activation of the Ras/MAPK pathway, which is essential for cell proliferation, differentiation, and survival. FRS2 also interacts with Shp2, linking FGFR activation to the phosphatidylinositol 3-kinase (PI3K) pathway, which regulates cell survival and metabolic processes. FRS2 is highly involved in developmental processes and is often implicated in diseases such as cancer, where FGFR signaling is dysregulated. Its role as a signaling hub makes it a critical component in cellular communication and a potential target for therapeutic interventions in FGFR-related disorders.
