Target

  • Function

    Accessory protein for MHC class-II antigen/T-cell receptor interaction. May regulate T-cell activation. Induces the aggregation of lipid rafts.
  • Sequence similarities

    Contains 3 Ig-like C2-type (immunoglobulin-like) domains.
    Contains 1 Ig-like V-type (immunoglobulin-like) domain.
  • Post-translational
    modifications

    Palmitoylation and association with LCK contribute to the enrichment of CD4 in lipid rafts.
  • Cellular localization

    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.

Question
Answer

Thanks for your call today and for your questions about our CD4 antibodies. Since neither ab28069 or ab34271 has been tested in a sandwich ELISA with ab51312, I can offer a discount off a future purchase if you buy one of these biotinylated CD4 antibodies now, test it in sandwich ELISA with ab28069 or ab34271, and submit feedback to us in the form of an Abreview. The discount would be worth of 1 free primary antibody. If you are interested in this offer, please follow these steps: 1. Reply to this e-mail to let me know that you would like to proceed and test one of these antibodies. I will then send a discount code. 2. Purchase ab28069 or ab34271 either by phone, fax, or online (www.abcam.com). 3. Test it in sandwich ELISA with ab51312. 4.
