Descriptions

Fibroblast growth factor receptor 3 (FGFR3) is one of the members of FGFR family belonging to the receptor tyrosine kinases (RTK) in cell proliferation, differentiation, migration, and maintenance of cellular homeostasis. FGFR3 consists of the ligand-binding region (immunoglobulin (Ig) domain 1-like domains) designated D1, D2, and D3, and a kinase domain. The D1 domain and the acid box (AB)-containing linker between D1 and D2 are involved in autoinhibition. Loss of D1 or the linker enhances the affinity of FGFR for FGF and HS and increases the signaling capacity of FGFR. Specifically, the AB region blocks the heparan sulfate (HS)-binding site on the D2 domain in cis to suppress HS-binding affinity of EGFR. D1 is dispensable for autoinhibition but plays a minor role in autoinhibition.
