    Western blot analysis of extracts from HT-29 (lane 2(20μg) and HT-29 (lane 3(40μg)using FGFR2 (HY-P80397) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% defatted milk powder in TBST for 2 hour at room temperature. The primary antibody (HY-P80397, 1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/3000) was used in 5% defatted milk powder in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (HY-P8004/HY-P8001, 1/10,000) was used for 1 hour at room temperature.

Background

  • Function

    FGFR2 encodes FGFR2b and FGFR2c isoforms with distinct expression domains and ligand specificity[1]. Mechanistically, FGF/FGFR signaling regulates lineage commitment, differentiation, proliferation, and apoptosis in development and adult homeostasis[2]. In disease models, FGFR2 alterations activate signaling in breast, gastric, cholangiocarcinoma, lung squamous, and oral squamous cancers[1][3][4]. Compared with related isoforms, FGFR2b-to-FGFR2c switching occurs during prostate and bladder cancer progression, linking splice regulation to epithelial-mesenchymal transition[1]. For experimental applications, FGFR2 mutation or amplification supports use of FGFR inhibitors, while extracellular-domain FGFR2 mutations can drive constitutive dimerization and inhibitor-sensitive transformation[1][4].

    Autophosphorylated. Binding of FGF family members together with heparan sulfate proteoglycan or heparin promotes receptor dimerization and autophosphorylation on several tyrosine residues. Autophosphorylation occurs in trans between the two FGFR molecules present in the dimer. Phosphorylation at Tyr-769 is essential for interaction with PLCG1;N-glycosylated in the endoplasmic reticulum. The N-glycan chains undergo further maturation to an Endo H-resistant form in the Golgi apparatus;Ubiquitinated. FGFR2 is rapidly ubiquitinated after autophosphorylation, leading to internalization and degradation. Subject to degradation both in lysosomes and by the proteasome

  • Subunit

    Monomer. Homodimer after ligand binding. Interacts predominantly with FGF1 and FGF2, but can also interact with FGF3, FGF4, FGF6, FGF7, FGF8, FGF9, FGF10, FGF17, FGF18 and FGF22 (in vitro). Ligand specificity is determined by tissue-specific expression of isoforms, and differences in the third Ig-like domain are crucial for ligand specificity. Isoform 1 has high affinity for FGF1 and FGF2, but low affinity for FGF7. Isoform 3 has high affinity for FGF1 and FGF7, and has much higher affinity for FGF7 than isoform 1 (in vitro). Affinity for fibroblast growth factors (FGFs) is increased by heparan sulfate glycosaminoglycans that function as coreceptors. Likewise, KLB increases the affinity for FGF19 and FGF21. Interacts with PLCG1, GRB2 and PAK4. Interacts with FLRT2 (By similarity)
