分子别名(Synonym)
GFR alpha like, GFR alpha-like, GFRAL, GRAL
表达区间及表达系统(Source)
Human GFR alpha-like, His Tag (GFA-H52H3) is expressed from human 293 cells (HEK293). It contains AA Ser 19 - Glu 351 (Accession # Q6UXV0-1).
Predicted N-terminus: Ser 19
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 39.7 kDa. The protein migrates as 43-60 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method / rFC method.
纯度(Purity)
>95% as determined by SDS-PAGE.
>95% as determined by SEC-MALS.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

背景介绍
GFRα样蛋白(亦称GDNF家族受体α样蛋白、GFRAL、C6orf144、UNQ9356、PRO34128)是一种特异性表达于脑干的受体蛋白。生长分化因子15(GDF15)作为一种循环蛋白,参与能量稳态调节、体重调控以及癌症与慢性疾病引发的恶病质等多种生理病理过程。最新研究发现,GDNF家族受体α样蛋白(GFRAL)是介导GDF15厌食效应的神经元性脑干受体,该受体通过响应代谢应激和毒素应激来调控进食行为、能量消耗及体重变化。当GFRAL与其配体GDF15结合后,会与RET受体形成复合物,通过激活MAPK和AKT信号通路诱导细胞内信号转导。
