描述

The VRK1 protein is a serine/threonine kinase that complexly regulates the cell cycle, nuclear condensation, and transcription. It critically induces Golgi disassembly during the cell cycle via PLK3 phosphorylation, thereby affecting Golgi fragmentation. VRK1 Protein, Human (sf9) is the recombinant human-derived VRK1 protein, expressed by Sf9 insect cells , with tag free. and with residual Gly-Pro in N-terminal (not related to functional changes), , , , mutation. The total length of VRK1 Protein, Human (sf9) is 396 a.a., with molecular weight of ~47 kDa.

研究背景

VRK1 是一种丝氨酸/苏氨酸激酶,复杂地参与细胞周期调节、核浓缩和转录控制。通过其多样化的功能,VRK1 对细胞过程表现出多方面的影响。值得注意的是,它在细胞周期期间的高尔基体分解中发挥着至关重要的作用,这一过程由有丝分裂期间 PLK3 的磷酸化启动,最终导致高尔基体断裂。VRK1 进一步调节 p53/TP53 的复杂网络,磷酸化“Thr-18”,并可能阻碍 p53/TP53 与 MDM2 之间的相互作用。为了应对 DNA 损伤,VRK1 磷酸化 KAT5,促进其与染色质的结合并增强组蛋白乙酰转移酶活性。此外,VRK1 通过磷酸化 BANF1、破坏其 DNA 结合能力、减少其与含有 LEM 结构域的蛋白质的相互作用以及触发其从细胞核重新定位到细胞质来影响核动力学。此外,VRK1 还靶向 ATF2,激活其转录活性,并进一步扩展这种多功能激酶的调控功能。

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
