描述

ACKR3 is an atypical chemokine receptor that precisely controls chemokine levels and localization through high-affinity binding, operating independently of ligand-driven signaling. It acts as an interceptor, internalization receptor, and chemokine scavenger for CXCL11 and CXCL12/SDF1, inducing β-arrestin recruitment, ligand internalization, and MAPK pathway activation. ACKR3 Protein, Human (Cell-Free, His, SUMO) is the recombinant human-derived ACKR3 protein, expressed by E. coli Cell-free , with N-6*His, N-SUMO labeled tag. The total length of ACKR3 Protein, Human (Cell-Free, His, SUMO) is 362 a.a., with molecular weight of 57.5 kDa.

研究背景

ACKR3 是一种非典型趋化因子受体,通过高亲和力趋化因子结合对趋化因子水平和定位进行精确控制,其运作独立于传统配体驱动的信号转导级联。作为拦截器、内化受体、趋化因子清除受体或趋化因子诱饵受体,ACKR3 与 CXCL11 和 CXCL12/SDF1 等趋化因子结合,而不激活 G 蛋白介导的信号转导。相反,趋化因子结合会诱导 β-抑制蛋白募集,导致配体内化和 MAPK 信号通路激活。在迁移的中间神经元中,ACKR3 对于调节 CXCR4 蛋白水平、调整其对趋化因子的反应至关重要。在神经胶质瘤细胞中,ACKR3 通过 MEK/ERK 途径转导信号,赋予细胞凋亡抵抗力并促进细胞生长和存活。虽然不影响正常造血祖细胞的迁移、粘附或增殖,但当恶性造血细胞中的 CXCL11 激活时,ACKR3 会通过 ERK1/2 磷酸化增强细胞粘附和迁移。此外,ACKR3 在 CXCR4 介导的细胞表面整合素激活中发挥调节作用,对心脏瓣膜发育至关重要。在动眼神经系统中,ACKR3 通过调节 CXCL12 水平来调节轴突引导。此外,作为 CXCR4 的共受体,ACKR3 在微生物感染期间与有限数量的 HIV 分离株合作。

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
