glycoprotein 160, an HIV precursor protein that is cleaved by the HIV protease enzyme into gp41 and gp120.
a glycoprotein in the outer envelope of HIV which enables the virus to enter human cells. The glycoprotein is produced by the viral env gene and cleaved into gp120 and gp41 fragments.
The "precursor" protein to both gp41 and gp120, gp160 is cleaved by viral enzymes into the two surface proteins at a late stage of viral assembly.
