A Conserved Acidic Residue in the C-Terminal Flexible Loop of HIV-1 Nef Contributes to the Activity of SERINC5 and CD4 Downregulation
The host transmembrane protein SERINC5 is incorporated into retrovirus particles and inhibits HIV-1 infectivity.The lentiviral Nef protein counteracts SERINC5 by downregulating it from the cell Girls Spring Dressy Set surface and preventing its incorporation into virions.The ability of Nef to antagonize the host factor varies in magnitude between d
