描述

The MAPKAPK3 protein is a stress-activated kinase involved in multiple cellular processes, including cytokine production and endocytosis. It is phosphorylated by p38-alpha/MAPK14 during stress, targets specific substrates, and has similarities to MAPKAPK2 but is less active. MAPKAPK3 Protein, Human (Active, sf9, GST) is the recombinant human-derived MAPKAPK3, expressed by Sf9 insect cells , with GST labeled tag. ,

研究背景

MAPKAPK3 蛋白是一种应激激活的丝氨酸/苏氨酸蛋白激酶,在细胞过程中发挥多种作用,包括细胞因子产生、内吞作用、细胞迁移、染色质重塑和转录调节。受到压力后,MAPKAPK3 被 MAP 激酶 p38-α/MAPK14 磷酸化并激活,导致特定底物磷酸化。MAPKAPK3 与 MAPKAPK2 具有功能相似性和底物特异性,表现出较低的激酶活性和蛋白质表达水平。它磷酸化 HSP27/HSPB1、KRT18、KRT20、RCSD1、RPS6KA3、TAB3 和 TTP/ZFP36 等关键蛋白。为了应对应激,MAPKAPK3 介导 HSP27/HSPB1 的磷酸化,导致 HSP27/HSPB1 从大的小热休克蛋白 (sHsps) 寡聚体上解离,并损害其伴侣活性。值得注意的是,MAPKAPK3 通过转录后调节 TNF 和 IL6 的产生在炎症反应中发挥作用。它通过磷酸化富含 AU 元素 (ARE) 的结合蛋白(例如 TTP/ZFP36)来实现这一目标,从而影响 TNF 和 IL6 mRNA 的稳定性和翻译。此外,MAPKAPK3 参与树突状细胞中的 Toll 样受体信号通路,有助于急性 TLR 诱导的巨胞饮作用。此外,它还充当 Polycomb 介导的抑制的调节剂,为其在细胞过程中的调节功能添加了另一层。

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
