Cayman Cd226 Extracellular Domain (Mouse, Recombinant; His-Tagged

Fibroblast growth factor 2 (FGF2), also known as basic FGF (BFGF), is a signaling polypeptide and member of the FGF family that has roles in cell growth and differentiation.^, Alternative translation produces multiple isoforms of FGF2: one 18 kDa low molecular weight isoform that is translated from a conventional AUG start codon and represents the core sequence common to all FGF2 isoforms, and several high molecular weight isoforms containing amino terminal extensions of the 18 kDa isoform that use CUG codons as alternative translational start sites. The 18 kDa isoform of FGF2 is found in the nucleus and cytoplasm and can be secreted by target cells. It forms a ternary complex with heparan sulfate proteoglycans and an FGF receptor (FGFR) at the cell surface resulting in activation of various signaling pathways, including Ras, Raf, MAPK, and ERK. High molecular weight isoforms are localized to the nucleus and induce signaling independent of FGFRs. FGF2 expression is spatially and temporally regulated during development and is concurrent with neurogenesis. Exogenous administration of FGF2 enhances neurogenesis in the subventricular zone and subgranular zone in an adult rat model of traumatic brain injury. It also reduces infarct size and increases myocardial capillary density in a canine model of myocardial infarction induced by permanent coronary artery occlusion. Lung and kidney expression of FGF2 is increased in a common marmoset model of Middle East respiratory syndrome coronavirus (MERS-CoV) infection. Cayman’s FGF2 (human, recombinant) protein can be used for cell-based assay applications. The protein consists of 147 amino acids and has a calculated molecular weight of 16.5 kDa.
