Application Abreviews Notes
ICC Use at an assay dependent concentration.
Flow Cyt 1/10 - 1/50. Use 10µl of the suggested working dilution to label 106 cells in 100µl.
IHC-Fr Use at an assay dependent dilution.


  • FunctionAccessory protein for MHC class-II antigen/T-cell receptor interaction. May regulate T-cell activation. Induces the aggregation of lipid rafts.
  • Sequence similaritiesContains 3 Ig-like C2-type (immunoglobulin-like) domains.
    Contains 1 Ig-like V-type (immunoglobulin-like) domain.
  • Post-translational
    Palmitoylation and association with LCK contribute to the enrichment of CD4 in lipid rafts.
  • Cellular localizationCell 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.
