Background: CD4
CD4 is a type I membrane glycoprotein belonging to the immunoglobulin superfamily. It is expressed predominantly on thymocytes and a subset of mature T lymphocytes. CD4 functions in collaboration with the T cell receptor in the recognition of peptide antigens that are presented by class II major histocompatibility complexes. CD4 also has been shown to be a coreceptor of HIV entry and specifically binds gp120, the external envelope glycoprotein of HIV.
  • Alternate Names:
    CD4; CD4 antigen; CD4 antigen (p55); CD4 molecule; CD4 receptor; CD4mut; T-cell surface antigen T4/Leu-3; T-cell surface glycoprotein CD4
