  • 描述
    大鼠单克隆抗体[GK1.5] to CD4 (Biotin)
  • 偶联物Biotin
  • 特异性Recognizes a determinant designated L3T4 present on mouse T-cell surface with an apparent molecular mass of 52kDa. The L3T4 antigen is expressed by the helper/inducer subset of mouse T-cells. The antigen is present on approximately 80% of thymocytes, 20% of spleen cells and 60% of lymph node cells. The expression of L3T4 correlates with class II MHC antigen reactivity on cloned T-cell lines.

  • 功能Accessory protein for MHC class-II antigen/T-cell receptor interaction. May regulate T-cell activation. Induces the aggregation of lipid rafts.
  • 序列相似性Contains 3 Ig-like C2-type (immunoglobulin-like) domains.
    Contains 1 Ig-like V-type (immunoglobulin-like) domain.
  • 翻译后修饰Palmitoylation and association with LCK contribute to the enrichment of CD4 in lipid rafts.
  • 细胞定位Cell membrane. Localizes to lipid rafts. Removed from plasma membrane by HIV-1 Nef protein that increases clathrin-dependent endocytosis of this antigen to target it to lysosomal degradation. Cell surface expression is also down-modulated by HIV-1 Envelope polyprotein gp160 that interacts with, and sequesters CD4 in the endoplasmic reticulum.
