CD333,Fgfr-3,Flg-2,FR3,HBGFR,Mfr3,sam3

Catalog Number P50071-M03H
Organism Species Mouse
Host Human Cells
Synonyms CD333,Fgfr-3,Flg-2,FR3,HBGFR,Mfr3,sam3
Molecular Weight The recombinant mouse FGFR3/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer consists of 595 amino acids and has a predicted molecular mass of 66 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rm FGFR3/Fc monomer is approximately 100-110 kDa due to glycosylation.
predicted N Glu 21
SDS-PAGE
Purity > 92 % as determined by SDS-PAGE
Protein Construction A DNA sequence encoding the extracellular domain (Met 1-Tyr 367) of mouse FGFR3 (NP_032036.2) precursor was fused with the C-terminal polyhistidine-tagged Fc region of human IgG1 at the C-terminus.
Bio-activity Measured by its ability to bind mouse aFGF in a functional ELISA.
Research Area Immunology |Cluster of Differentiation (CD) |Other CD Antigen
Formulation Lyophilized from sterile PBS, pH 7.4
1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
Background FGFR3, also known as CD333, is a member of the fibroblast growth factor receptor (FGFR) family, with its amino acid sequence being highly conserved between members and among divergent species. FGFR family members differ from one another in their ligand affinities and tissue distribution. FGFRs are transmembrane catalytic receptors that have intracellular tyrosine kinase activity. Mutations in FGFR genes are the cause of several human developmental disorders characterized by skeletal abnormalities such as achondroplasia, and upregulation of FGFR expression may lead to cell transformation and cancer. FGFR3, a full-length representative protein would consist of an extracellular region, composed of three immunoglobulin-like domains, a single hydrophobic membrane-spanning segment and a cytoplasmic tyrosine kinase domain. The extracellular portion of FGFR3 interacts with fibroblast growth factors, setting in motion a cascade of downstream signals, ultimately influencing mitogenesis and differentiation. FGFR3 binds acidic and basic fibroblast growth hormone and plays a role in bone development and maintenance. Mutations in FGFR3 gene lead to craniosynostosis and multiple types of skeletal dysplasia. Three alternatively spliced transcript variants that encode different protein isoforms have been described. CD333 is the receptor for acidic and basic fibroblast growth factors.
