PARP14 蛋白, Human (His, Strep)

目录号: HY-P701952
产品使用指南

PARP14 蛋白是一种 ADP-核糖基转移酶,与 PARP1PARP2 不同,它独特地对 STAT1STAT6 等靶蛋白上的谷氨酸残基进行单 ADP 核糖基化。它在“Glu-657”和“Glu-705”处催化 STAT1 单 ADP 核糖基化,减少 STAT1 磷酸化并抑制 IFNG 刺激后巨噬细胞中促炎细胞因子的产生。PARP14 蛋白, Human (His, Strep) 是重组的 PARP14 蛋白,由 E. coli 表达,带有 N-Strep, N-8*His 标签。PARP14 蛋白, Human (His, Strep) 全长 180 个氨基酸。

描述

The PARP14 protein is an ADP-ribosyltransferase that uniquely mono-ADP-ribosylates glutamic acid residues on target proteins such as STAT1 and STAT6, unlike PARP1 and PARP2. It catalyzes STAT1 mono-ADP ribosylation at “Glu-657” and “Glu-705”, reduces STAT1 phosphorylation and inhibits the production of pro-inflammatory cytokines in macrophages following IFNG stimulation. PARP14 Protein, Human (His, Strep) is the recombinant human-derived PARP14 protein, expressed by E. coli , with N-Strep, N-8*His labeled tag. The total length of PARP14 Protein, Human (His, Strep) is 180 a.a., .

研究背景

PARP14 蛋白是一种 ADP-核糖基转移酶,可促进靶蛋白上谷氨酸残基的单 ADP-核糖基化,与 PARP1PARP2 的区别在于它无法介导多 ADP-核糖基化。具体来说,它已被证明可以催化 STAT1 在“Glu-657”和“Glu-705”处的单 ADP 核糖基化,导致 STAT1 磷酸化减少,并随后在 IFNG 刺激后对巨噬细胞中促炎细胞因子产生的负调节。然而,ADP-核糖基化在阻止 STAT1 磷酸化中的确切作用一直存在争议,有人认为这种抑制可能是 STAT1“Lys-703”苏糖化的结果。此外,PARP14 单 ADP 核糖基化 STAT6,增强 STAT6 依赖性转录,并且在巨噬细胞中,它通过促进 STAT6 磷酸化,响应 IL4 刺激而正向调节 MRC1 表达。此外,PARP14 参与 PARP9 的单 ADP 核糖基化。

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
