VRK3 蛋白, Human (Sf9, His, GST)

目录号: HY-P701725
产品使用指南

尽管处于非活性激酶状态,VRK3 蛋白通过增强 DUSP3 的磷酸酶活性来至关重要地调节 ERK 活性。与 DUSP3 的相互作用至关重要,因为它可以使细胞核中的 ERK 去磷酸化并失活。VRK3 还与小型 GTPase RAN 相互作用,形成分子相互作用网络,将其定位为控制 ERK 活性和核细胞过程的信号通路中的关键调节剂。VRK3 蛋白, Human (Sf9, His, GST) 是重组的 VRK3 蛋白,由 Sf9 insect cells 表达,带有 N-8*His, N-GST 标签。VRK3 蛋白, Human (Sf9, His, GST) 全长 473 个氨基酸。

描述

Despite its inactive kinase state, VRK3 protein crucially regulates ERK activity by enhancing the phosphatase activity of DUSP3. The interaction with DUSP3 is pivotal as it dephosphorylates and inactivates ERK in the nucleus. VRK3, also interacting with the small GTPase RAN, forms a network of molecular interactions, positioning it as a key modulator in signaling pathways controlling ERK activity and nuclear cellular processes. VRK3 Protein, Human (Sf9, His, GST) is the recombinant human-derived VRK3 protein, expressed by Sf9 insect cells , with N-8*His, N-GST labeled tag. The total length of VRK3 Protein, Human (Sf9, His, GST) is 473 a.a., .

研究背景

VRK3 蛋白尽管处于非活性激酶状态,但通过促进 DUSP3 的磷酸酶活性,在 ERK 活性的调节中发挥着至关重要的作用。这种相互作用至关重要,因为 DUSP3 特异性地使细胞核内的 ERK 去磷酸化和失活。除了与 DUSP3 相关外,VRK3 还与小型 GTPase RAN 相互作用,表明存在分子相互作用网络。通过这些关联,VRK3 成为复杂信号通路中的关键调节剂,参与控制细胞核内的 ERK 活性和细胞过程。

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
