  30. Cell Vol 89, p263 (1997) Chan et al.Core Structure of gp41 from the HIV Envelope GlycoproteinThe envelope glycoprotein of human immunodeficiency virus type 1 (HIV-1) consists of a complex of gp120 and gp41. gp120 determines viral tropism by binding to target-cell receptors, while gp41 mediates fusion between viral and cellular membranes.
