The glycoprotein CD4 is a co-receptor. A co-receptor is "a cell surface receptor, which, when bound to its respective ligand, modulates antigen receptor binding or affects cellular activation after antigen-receptor interactions." (MediLexicon)
it binds with several signaling molecules as it has shape that is complementary to signaling molecules.
A glycoprotein is composted of a sugar (glyco-) and conjugated proteins.
The surface of the HIV virion contains a glycoprotein called gp120 which allows it to attach to human immune system cells. The T cells of the immune systemhave a receptor on their cell membrane called CD45. A strong interaction between CD45 and gp120 has been shown.
