描述

RBCK1 is an E3 ubiquitin protein ligase that cooperates with specific E2 enzymes such as UBE2L3/UBCM4 to transfer ubiquitin to substrates. It acts as an E3 ligase that oxidizes IREB2, relying on heme and oxygen for IREB2 ubiquitination. RBCK1 Protein, Human is the recombinant human-derived RBCK1 protein, expressed by E. coli , with tag free. The total length of RBCK1 Protein, Human is 509 a.a., .

研究背景

RBCK1 蛋白充当 E3 泛素蛋白连接酶,从特定 E2 酶(包括 UBE2L3/UBCM4)接收泛素,并将其转移到底物上。它充当氧化 IREB2 的 E3 连接酶,需要血红素和氧气来实现 IREB2 泛素化。RBCK1 促进 TAB2 和 IRF3 的泛素化和蛋白酶体降解。作为 LUBAC 复合物的一部分,RBCK1 催化线性多聚泛素链与底物的缀合,这对于 NF-kappa-B 激活和炎症调节至关重要。LUBAC 复合物被招募到 TNF-R1 信号复合物成分中,有助于复合物稳定性并防止 TNF 诱导的细胞死亡。RBCK1 与 OTULIN 一起调节血管生成过程中的经典 Wnt 信号传导,并结合各种连接类型的多聚泛素。此外,LUBAC 复合物通过在入侵细胞质的细菌周围形成泛素外壳,在先天免疫中发挥作用,充当异体吞噬的“吃我”信号并促进 NF-kappa-B 激活。

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
