Background:
Mouse F4/80 also named as EMR1 and Gpf480 is a 160-kDa cell surface glycoprotein which is a member of the EGF TM7 family.The F4/80 molecule is solely expressed on the surface of macrophages and serves as a marker for mature macrophage tissues including Kupffer cells in liver splenic red pulp macrophages brain microglia gut lamina propria and Langerhans cells in the skin.The function of F4/80 is unclear but it is speculated to be involved in macrophage adhesion events cell migration or as a G protein-coupled signaling component of macrophages.
