Human Megalin Protein, His Tag
分子别名(Synonym)
DBS, GP330, LRP-2
表达区间及表达系统(Source)
Human Megalin Protein, His Tag (MEN-H52H4) is expressed from human 293 cells (HEK293). It contains AA Pro 3510 - Lys 3964 (Accession # P98164).
Predicted N-terminus: Pro 3510
蛋白结构(Molecular Characterization)

This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 53.3 kDa. The protein migrates as Band dispersion 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)
>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
该基因编码的蛋白——低密度脂蛋白相关蛋白2(LRP2/megalin)——是一种多配体内吞受体,广泛表达于多种组织,但主要存在于肾脏等吸收性上皮组织。该糖蛋白具有巨大的氨基端胞外结构域、单个跨膜结构域及较短的羧基端胞质尾。其胞外配体结合域可结合多种大分子,包括白蛋白、载脂蛋白B/E及脂蛋白脂肪酶。
LRP2蛋白对脂蛋白、固醇、维生素结合蛋白及激素等配体的重摄取至关重要,同时参与细胞信号传导:胞外配体包括甲状旁腺激素与形态发生素音猬因子(sonic hedgehog),胞质配体则含MAP激酶支架蛋白和JNK互作蛋白。该膜受体的循环利用受其胞质域磷酸化调控。此基因突变可导致Donnai-Barrow综合征(DBS)及眼-耳-肾综合征(FOAR)。
