Figure 2

Schematic representation of HIV-1 gp41. The abbreviations represent the fusion peptide (FP); the fusion peptide proximal domain (FPPR); the N-terminal helical region (N-HR), the immunodominant loop region, the C-terminal helical region (C-HR), the membrane proximal region (MPER) and the transmembrane region (TM). The protein is numbered according to the HXB2 HIV-1 strain. The figure was adapted from [23].
