CD161 蛋白, Cynomolgus (HEK293, His)

目录号: HY-P77592
产品使用指南

CD161 蛋白通过激活特定酸性鞘磷脂酶/SMPD1、提高神经酰胺水平,在抑制 NK 细胞毒性方面发挥着至关重要的作用。激活会刺激 AKT1/PKB 和 RPS6KA1/RSK1 激酶,增强抗 CD3 诱导的 T 细胞增殖。作为凝集素,CD161 与 Gal-alpha(1,3)Gal 和 N-乙酰基乳糖胺表位结合,充当 CLEC2D/LLT1 的配体。CD161 作为同二聚体存在,与酸性鞘磷脂酶/SMPD1 相互作用,有助于其多方面的免疫调节功能。CD161 蛋白, Cynomolgus (HEK293, His) 是重组的 CD161 蛋白,由 HEK293 表达,带有 C-His 标签。CD161 蛋白, Cynomolgus (HEK293, His) 全长 161 个氨基酸,分子量为 38-48 kDa。

描述

CD161 Protein plays a crucial role in inhibiting NK cell cytotoxicity by activating specific acid sphingomyelinase/SMPD1, elevating ceramide levels. Activation stimulates AKT1/PKB and RPS6KA1/RSK1 kinases, enhancing anti-CD3-induced T-cell proliferation. As a lectin, CD161 binds to Gal-alpha(1,3)Gal and N-acetyllactosamine epitopes, acting as a ligand for CLEC2D/LLT1. Existing as a homodimer, CD161 interacts with acid sphingomyelinase/SMPD1, contributing to its multifaceted immune regulatory functions. CD161 Protein, Cynomolgus (HEK293, His) is the recombinant cynomolgus-derived CD161 protein, expressed by HEK293 , with C-His labeled tag. The total length of CD161 Protein, Cynomolgus (HEK293, His) is 161 a.a., with molecular weight of 38-48 kDa.

研究背景

CD161 在抑制自然杀伤 (NK) 细胞的细胞毒性中发挥着至关重要的作用。激活后,CD161 会刺激特定的酸性鞘磷脂酶/SMPD1,导致细胞内神经酰胺水平显着增加。激活过程还会刺激 AKT1/PKB 和 RPS6KA1/RSK1 激酶,并显着增强抗 CD3 诱导的 T 细胞增殖。作为凝集素,CD161 与末端碳水化合物 Gal-alpha(1,3)Gal 表位和 N-乙酰基乳糖胺表位结合。此外,它还充当 CLEC2D/LLT1 的配体,抑制 NK 细胞介导的细胞毒性和靶细胞中的干扰素 γ 分泌。CD161 作为具有二硫键的同型二聚体存在,与酸性鞘磷脂酶/SMPD1 相互作用,有助于其在免疫反应中的多方面调节功能[1][2][3]

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
