Active Recombinant Human FGFR3(447-761) Protein, N-His-tagged

Specification :
| Description : Fibroblast growth factor (FGF) superfamily consists of 23 members, all of which contain a conserved 120 amino acid (aa) core region that contains six identical, interspersed amino acids. Based on the pI factor, two main groups of FGF are named: acidic FGF (aFGF) and basic FGF (bFGF). The superfamily members act extracellularly through four tyrosine kinase FGF receptors (FGR1 through FGR4), with multiple specificities noted for almost all FGFs. Biological binding of aFGF to its receptors will result in phosphorylation of the receptor and non-receptor proteins and generate its function. FGR3 (FGFR-3, Fibroblast growth factor receptor 3, EC 2.7.1.112) is expressed mainly in bone, central nervous system and tumors. Inhibition of FGR3 may be useful in the treatment of dwarfism as well as some tumors. | Source : Sf21 | Species : Human | Tag : His | Protein length : 447-761 aa | Form : 0.561mg/ml in 50mM Tris/HCl pH7.5, 150mM NaCl, 0.1mM EGTA, 0.03% Brij-35, 270mM sucrose, 1mM benzamidine, 0.2mM PMSF, 0.1% 2-mercaptoethanol.
