描述

RSK2 is a kinase downstream of ERK signaling and plays a critical role in mediating mitosis and stress responses. It activates transcription factors (CREB1, ETV1, NR4A1), affecting proliferation, survival and differentiation. RSK2 Protein, Human is the recombinant human-derived RSK2 protein, expressed by E. coli , with tag free. The total length of RSK2 Protein, Human is 341 a.a., .

研究背景

RSK2 是一种丝氨酸/苏氨酸蛋白激酶,在 ERK(MAPK1/ERK2 和 MAPK3/ERK1)信号传导下游发挥作用,协调促有丝分裂和应激诱导的细胞反应。它在 CREB1、ETV1/ER81 和 NR4A1/NUR77 等转录因子的激活中发挥着关键作用,有助于细胞增殖、存活和分化。RSK2 通过磷酸化 RPS6 和 EIF4B 来调节翻译,促进预起始复合物的组装。此外,它还复杂地调节 mTOR 信号传导,抑制 BAD 和 DAPK1 的促凋亡功能,并参与细胞存活机制。在成纤维细胞中,RSK2 对于 EGF 刺激的 CREB1 和组蛋白 H3 磷酸化至关重要,从而导致立即早期基因的转录激活。在促有丝分裂刺激下,它磷酸化并激活 NR4A1/NUR77 和 ETV1/ER81 转录因子。响应胰岛素衍生信号,RSK2 通过磷酸化 GSK3B 间接影响基因的转录调控。此外,RSK2 参与 mTOR 营养感应途径,介导 TSC2 磷酸化并调节 mTORC1 活性。此外,RSK2 发挥多种作用,包括促进肝星状细胞的存活、通过磷酸化 CDKN1B 调节细胞周期,以及通过介导 ATF4 磷酸化作为成骨细胞分化的调节剂。在各种细胞环境中,RSK2 参与复杂的调控网络,负向调节 EGF 诱导的 MAPK1/3 磷酸化、磷酸化 SOS1,并控制 RPS6KA-EPHA2 信号通路以影响细胞迁移。

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
