描述

The EIF3G protein is an RNA-binding component of the eIF-3 complex that initiates protein synthesis by promoting the recruitment of factors to form the 43S PIC. EIF3G is critical in both mRNA recruitment and AUG recognition scanning. EIF3G Protein, Human (His-SUMO) is the recombinant human-derived EIF3G protein, expressed by E. coli , with N-SUMO, N-6*His labeled tag. The total length of EIF3G Protein, Human (His-SUMO) is 319 a.a., with molecular weight of 51.5 kDa.

研究背景

EIF3G 蛋白在真核翻译起始因子 3 (eIF-3) 复合物中充当 RNA 结合成分,在蛋白质合成起始的各个步骤中发挥着关键作用。eIF-3 复合物与 40S 核糖体结合,促进必需因子的募集,例如 eIF-1、eIF-1A、eIF-2:GTP:methionyl-tRNAi 和 eIF-5,以形成 43S 前体起始复合物(43S PIC)。随后,EIF3G 作为 eIF-3 复合物的一部分,促进 mRNA 募集到 43S PIC 并扫描 AUG 识别。此外,它在终止后核糖体复合物的拆卸和回收中发挥着关键作用,防止 40S 和 60S 核糖体亚基在启动前过早连接。eIF-3 复合物(包括 EIF3G)选择性地靶向并启动参与细胞增殖的特定 mRNA 的翻译,从而影响细胞周期、分化和凋亡等过程。通过不同的 RNA 茎环结合模式,EIF3G 可以发挥翻译激活或抑制作用。在微生物感染(例如 FCV 感染)的情况下,EIF3G 参与导致特定病毒蛋白翻译的核糖体终止-重新启动事件。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
