BackgroundNatural killer cell receptor 2B4 is a type I transmembrane glycoprotein in the SLAM subgroup of the CD2 protein family.2B4 interacts with CD48, while other SLAM family proteins interact homophilically. Three additional splice variants of human 2B4 have deletions of the short region between the Ig-like domains, the second Ig-like domain, or a portion of the cytoplasmic tail.2B4 is expressed on all NK cells, γδ T cells, monocytes, some CD4+ and CD8+ T cells, and some dendritic cells. CD48 mediates 2B4+ cell interactions with nearly all hematopoietic cell types, including cells of the same type. 2B4/CD48 signaling cooperates with other receptor systems to either promote or inhibit NK and CD8+ T cell activation. The inhibitory activities are distinct from those of MHC I restricted inhibitory NK cell receptors. Ligation of 2B4 with antibodies or CD48 constructs can either directly trigger inhibitory signaling or disrupt an inhibitory interaction, leading to cellular activation. The inhibitory effect is associated with the long form of 2B4, while the activation is associated with the short form. 2B4 can also induce signaling through CD48.

FAQ
  • 如何提高重组蛋白的可溶性表达?

    可优化表达条件(如降低诱导温度、调整IPTG浓度)、使用促溶标签(如SUMO、GST)、共表达分子伴侣,或尝试不同宿主系统(如哺乳动物细胞或昆虫细胞)以提高可溶性蛋白产量。

  • 重组蛋白纯化常用的方法有哪些?

    常用的纯化方法包括亲和层析(如His-Tag、GST-Tag)、离子交换层析、疏水相互作用层析(HIC)和凝胶过滤层析。具体方法取决于蛋白特性和标签类型。
