Frizzled-4产品信息

英文名称：Frizzled-4

中文名称：卷曲蛋白-4

靶点别称：FZD4,Frizzled-4,CD344

物种：Human

标签：Fc Tag

属性：Protein

标记：Unconjugated

表达区间及表达系统（Source）

Human Frizzled-4, Fc Tag (FZ4-H5250) is expressed from human 293 cells (HEK293). It contains AA Phe 37 - Glu 180 (Accession # AAI14528).

Predicted N-terminus: Phe 37

蛋白结构（Molecular Characterization）

This protein carries a human IgG1 Fc tag at the C-terminus.

The protein has a calculated MW of 42.9 kDa. The protein migrates as 50-55 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

内毒素（Endotoxin）

Less than 1.0 EU per μg by the LAL method.

纯度（Purity）

>95% as determined by SDS-PAGE.

制剂（Formulation）

Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

-20°C to -70°C for 12 months in lyophilized state;

-70°C for 3 months under sterile conditions after reconstitution.

背景（Background）

Frizzled-4（FZD4）也被称为FzE4、CD344，属于G蛋白偶联受体Fz/Smo家族。大多数卷曲受体与β-连环蛋白规范信号通路偶联，导致凌乱蛋白的激活、GSK-3激酶的抑制、β-连环素的核积累和Wnt靶基因的激活。FZD4包含一个FZ（卷曲）结构域。FZD4可能参与组织形态发生和/或分化组织中极性信息的转导和细胞间传递。FZD4与MAGI3和去甲灵（NDP）相互作用。
