分子别名(Synonym)
MET,AUTS9,HGFR,RCCP2,c-Met
表达区间及表达系统(Source)
Biotinylated Human HGF R, Avitag,His Tag (MET-H82E1) is expressed from human 293 cells (HEK293). It contains AA Glu 25 - Thr 932 (Accession # P08581-1).
Predicted N-terminus: Glu 25 (α chain) & Ser 308 (β chain)
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 32.5 kDa (α chain) & 72.7 kDa (β chain). The protein migrates as 40-50 kDa (α subunit) and 90-100 kDa (β subunit) when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
标记(Labeling)

蛋白标记度(Protein Ratio)
Passed as determined by the HABA assay / binding ELISA.
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method / rFC method.
纯度(Purity)
>90% as determined by SDS-PAGE.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介绍
肝细胞生长因子受体(HGFR)又称间质-上皮转化因子(MET)或c-Met,是一种糖基化受体酪氨酸激酶,在上皮形态发生和癌症发展中起核心调控作用。该受体具有酪氨酸激酶活性,其前体单链蛋白经翻译后剪切形成α与β亚基,通过二硫键连接组成成熟受体。HGFR通常表达于上皮源性细胞,而其配体HGF仅由间质源性细胞产生。当HGF刺激时,HGFR诱导的系列生物学反应共同启动"侵袭性生长"程序。该受体在癌症中的异常活化与不良预后相关:失控的HGFR信号会触发肿瘤增殖、促进营养供给性血管新生、并导致癌症远处转移(转移)。HGFR在肾癌、肝癌、胃癌、乳腺癌及脑瘤等多种恶性肿瘤中呈现异常活化。正常情况下仅干细胞与祖细胞表达HGFR,而肿瘤干细胞被认为劫持了正常干细胞表达HGFR的能力,成为癌症持续存在及全身转移的根源。HGFR基因的多种突变与乳头状肾细胞癌相关,其介导的侵袭性生长程序可同时触发细胞增殖与形态发生。
