Structure, membrane topology and influence of cholesterol of the membrane proximal region: transmembrane helical anchor sequence of gp41 from HIV

open access: yesScientific Reports, 2020
During the first steps of HIV infection the Env subunit gp41 is thought to establish contact between the membranes and to be the main driver of fusion.

Increased infectivity in human cells and resistance to antibody-mediated neutralization by truncation of the SIV gp41 cytoplasmic tail

open access: yesFrontiers in Microbiology, 2013
The role of antibodies in protecting the host from human immunodeficiency virus type 1 (HIV-1) infection is of considerable interest, particularly because the RV144 trial results suggest that antibodies contribute to protection.

HIV-1 Envelope Glycoprotein Trafficking and Viral Transmission

open access: yesProceedings, 2020
HIV-1 encodes an envelope glycoprotein complex (Env) containing a long cytoplasmic tail (CT) harboring trafficking motifs implicated in Env incorporation into virions.

Maturation-induced cloaking of neutralization epitopes on HIV-1 particles. [PDF]

open access: yesPLoS Pathogens, 2011
To become infectious, HIV-1 particles undergo a maturation process involving proteolytic cleavage of the Gag and Gag-Pol polyproteins. Immature particles contain a highly stable spherical Gag lattice and are impaired for fusion with target cells.

The Glu143 Residue Might Play a Significant Role in T20 Peptide Binding to HIV-1 Receptor gp41: An In Silico Study

open access: yesMolecules, 2022
Despite the enormous efforts made to develop other fusion inhibitors for HIV, the enfuvirtide (known as T20) peptide is the only approved HIV-1 inhibitory drug so far.

Alanine Scanning Mutants of the HIV gp41 Loop [PDF]

open access: yesJournal of Biological Chemistry, 2005
Based on mutagenesis and structural studies of human immunodeficiency virus (HIV) envelope proteins, the loop region of gp41 is thought to directly interact with gp120. The importance of the HIV gp41 loop region to envelope function has been systematically examined by alanine scanning of all gp41 loop residues and the subsequent characterization of the

Receptor Activation of HIV-1 Env Leads to Asymmetric Exposure of the gp41 Trimer.

open access: yesPLoS Pathogens, 2016
Structural rearrangements of HIV-1 glycoprotein Env promote viral entry through membrane fusion. Env is a symmetric homotrimer with each protomer composed of surface subunit gp120 and transmembrane subunit gp41.

Targeting a Conserved Lysine in the Hydrophobic Pocket of HIV-1 gp41 Improves Small Molecule Antiviral Activity

open access: yesViruses, 2022
Human Immunodeficiency virus (HIV-1) fusion is mediated by glycoprotein-41, a protein that has not been widely exploited as a drug target. Small molecules directed at the gp41 ectodomain have proved to be poorly drug-like, having moderate efficacy, high ...

Chemical Optimization of Temporin A–L Peptides: From Native Isoforms to Enhanced Antimicrobial Analogs

open access: yesChemMedChem, Volume 21, Issue 15, 14 August 2026.
Temporins, among antimicrobial peptides, are short frog‐derived molecules with potent antibacterial activity. This review highlights chemical optimization strategies applied to temporins A–L, showing how sequence tuning modulates structure, stability, and selectivity, enabling improved activity against resistant pathogens.

HIV-1 gp41 and TCRalpha trans-membrane domains share a motif exploited by the HIV virus to modulate T-cell proliferation. [PDF]

open access: yesPLoS Pathogens, 2010
Viruses have evolved several strategies to modify cellular processes and evade the immune response in order to successfully infect, replicate, and persist in the host.
