CD4 is a 56-58 kDa type I transmembrane glycoprotein belonging to the immunoglobulin superfamily. It is expressed on a variety of cell types including T helper cells, follicular helper cells, neurons, T regulatory cells, microglia, and monocytes. 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. Over aa 25-401, canine CD4 shares 56% amino acid identity with human CD4.
