MARCH8 targets cytoplasmic lysine residues of various viral envelope glycoproteins

The host transmembrane protein MARCH8 is a RING finger E3 ubiquitin ligase that downregulates various host transmembrane proteins, such as MHC-II. We have recently reported that MARCH8 expression in virus-producing cells impairs viral infectivity by reducing virion incorporation of not only HIV-1 envelope glycoproteins but also vesicular stomatitis virus G-glycoprotein...
