IGSF3 蛋白, Human (HEK293, His)

IGSF3 Protein, an immunoglobulin-like superfamily member, has a Glu-Trp-Ile (EWI) motif in extracellular region. IGSF3 is a developmentally regulated protein that controls neuronal morphogenesis. IGSF3 controls the differentiation of granule cells, axonal growth and branching. IGSF3 is a novel regulator of neuronal morphogenesis that might function through interactions with multiple partners including the tetraspanin TSPAN7. IGSF3 functions as a tumor promoter and induces hepatocellular carcinoma (HCC) cancer cell growth and invasion by acting through the NF-κB signaling pathways^[1][2]. IGSF3 Protein, Human (HEK293, His) is the recombinant human-derived IGSF3 protein, expressed by HEK293 , with C-His labeled tag. The total length of IGSF3 Protein, Human (HEK293, His) is 1105 a.a., with molecular weight of 130-150 KDa.

IGSF3 是一种膜蛋白，在大脑发育过程中以神经元特异性和时间依赖性方式表达。在发育中的大脑中，IGSF3 与四跨膜蛋白 TSPAN7 形成复合物，TSPAN7 是一种膜蛋白，在多种形式的 X 连锁智力障碍中发生突变^[1]。
IGSF3 位于染色体 1p13.1 上，是免疫球蛋白 (Ig) 超家族的一部分。IGSF3 在异种移植肿瘤模型中促进体内 HCC 的生长。IGSF3 增强 HCC 细胞系的细胞周期进程、细胞生长、迁移和侵袭。通过敲低减少 IGSF3 的表达会显着降低 p-NF-κB/NF-κB 和 p-IKBα/IKBα 的水平，而过表达 IGSF3 则会产生相反的结果^[2]。

  Greater than 95% as determined by reducing SDS-PAGE.

无菌粉末

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
