详细介绍

Fibroblast growth factor receptor 4 (FGF R4), also known as CD334, is a 110 kDa glycosylated transmembrane receptor tyrosine kinase. Within the ECD, human FGF R4 shares 90% and 88% aa sequence identity with mouse and rat FGF R4, respectively. A 65 kDa Nterminally truncated isoform lacks the signal peptide and first two Iglike domains. This isoform is produced in human pituitary adenomas and is constitutively phosphorylated and oncogenic. FGF R4 is widely expressed during embryonic development and in adult liver, kidney, and lung. It binds FGF acidic, FGF basic, FGF8, -15, and -19. FGF R4 supports glucose tolerance and insulin sensitivity and protects against hyperlipidemia. It is downregulated in the liver during fasting and is upregulated by insulin. It can exert either proliferative or apoptotic effects on hepatocytes.

产品性质

别名（Synonyms）	CD334, FGF R4, FGFR4, FGFR-4, MGC20292, JTK2, TKF
Uniprot No.	P22455
表达区间及表达系统（Source）	Recombinant Human FGFR4 Protein is expressed from HEK293 Cells with hFc tag at the C-terminal. It contains Leu22-Asp369.
分子量(Molecular Weight)	Approximately 65.3 kDa. Due to glycosylation, the protein migrates to 80-95 kDa based on Tris-Bis PAGE result.
外观(Physical Appearance）	Sterile Filtered White lyophilized (freeze-dried) powder.
纯度（Purity）	> 95% as determined by SDS-PAGE and HPLC
活性（Activity）	Testing in progress
内毒素（Endotoxin）	< 1.0 EU per 1μg of the protein by the LAL method.
制剂（Formulation）	Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.
复溶（Reconstitution）	Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL` is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water.
