CD161 蛋白, Human (Biotinylated, HEK293, His-Avi)

CD161 protein plays a crucial role in inhibiting NK cell toxicity by activating specific acid sphingomyelinase/SMPD1 and increasing ceramide levels. Activation stimulates AKT1/PKB and RPS6KA1/RSK1 kinases, enhancing anti-CD3-induced T cell proliferation. CD161 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived CD161 protein, expressed by HEK293 , with C-Avi, C-His labeled tag. The total length of CD161 Protein, Human (Biotinylated, HEK293, His-Avi) is 159 a.a., with molecular weight of 35-43 kDa.

CD161 蛋白在抑制自然杀伤 (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。

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. Normally 5% trehalose is added as protectant before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
