背景信息
CD4 is a transmembrane glycoproteinof the immunoglobulin super-family (IgSF), containing four extracellular Ig-like domains, ahydrophobic transmembrane region and a 40-residue cytoplasmictail. CD4 is expressed T helper cells, majority of thymocytes, monocytes, macrophages, and dendritic cells.CD4 is an accessory protein for MHC class-II antigen/T-cell receptor interactionand it is involved in T cell differentiation, development and activation by interacting with antigen-presenting cells (APCs). The cytoplasmic tail of CD4 associates with the Lck kinase, which in turn activates the signaling components of the T cell receptor (TCR)-CD3 complexes.CD4 also serves as a receptor for human immunodeficiency virus (HIV) by binding to the viral envelope glycoprotein gp120.
