Datasheet

MSDS

Human fibroblast growth factor receptor 3 (FGFR3) is a cell surface receptor belonging to the immunoglobulin superfamily functioning as a receptor tyrosine kinase (RTK). FGFR3 can form ligand-dependent and ligand-independent dimers. The recombinant FGFR3 dimer protein (CSP-25131-03) is a cis-homodimer (cis-dimer) and contains a FGFR3 extracellular domain (UniProt# P22607, amino acids Glu23-Gly375) fused with a proprietary cis-dimer motif followed by a tandem His-Avi tag at the C-terminus. This dimeric protein is expressed in HEK293T cells. The recombinant human FGFR3 dimer protein is bioactive and can bind to fibroblast growth factor 1 (FGF-1). It also binds FGFR3-specific antibodies. This FGFR3 dimer can be used as an antigen for in vitro assays and antibody screening, and as an immunogen for immunization to generate antibodies targeting more conformational epitopes.

Background and Alternate Names

Human fibroblast growth factor receptor 3 (FGFR3) is a cell surface receptor belonging to the immunoglobulin superfamily and a transmembrane receptor tyrosine kinase (RTK) that belongs to the FGFR family. FGFR3 is also known as ACH, cluster of differentiation 333 (CD333), CEK2, HSFGFR3EX, and JTK4. FGFR3 contains an extracellular domain with three immunoglobulin-like (Ig-like) subdomains (D1, D2 and D3), followed by a transmembrane, and an intracellular domain. Dimerization of FGFRs is necessary for activation and they can homodimerize and heterodimerize in both the presence and absence of ligand. FGFRs bind fibroblast growth factors (FGFs) leading to phosphorylation and triggering signaling cascades. FGFR3 is involved in diseases including achondroplasia, hypochondroplasia, and bladder cancer. Therefore, a recombinant protein mimicking the FGFR3 dimer conformation can be critical for cancer therapeutic discovery.
