Antigenic and immunosuppressive properties of a trimeric recombinant transmembrane envelope protein gp41 of HIV-1. [PDF]
The transmembrane envelope (TM) protein gp41 of the human immunodeficiency virus-1 (HIV-1) plays an important role during virus infection inducing the fusion of the viral and cellular membranes.

HIV-1 Envelope Protein gp41: An NMR Study of Dodecyl Phosphocholine Embedded gp41 Reveals a Dynamic Prefusion Intermediate Conformation [PDF]
Human immunodeficiency viral (HIV-1) fusion is mediated by the viral envelope gp120/gp41 complex (ENVelope glycoprotein). After gp120 shedding, gp41 is exposed and elicits membrane fusion via a cascade of conformational changes. In contrast to prefusion and postfusion conformation, little is known about any intermediate conformation.

Investigating the role of a conserved hydrophobic pocket of gp41 in the anti-HIV activity of fusion inhibitors. [PDF]
Abstract Membrane fusion between HIV and host cells requires interaction between the N‐terminal and C‐terminal repeat regions (NHR and CHR) of the gp41 envelope subunit. A deep hydrophobic pocket (HP) on the surface of NHR is considered crucial in this interaction.

Background HIV-1 envelope gp41 is a transmembrane protein that promotes fusion of the virus with the plasma membrane of the host cells required for virus entry. In addition, gp41 is an important target for the immune response and development of antiviral

HIV-1 gp41 Fusion Intermediate: A Target for HIV Therapeutics
Human immunodeficiency virus (HIV)-1 infection is initiated by the binding of gp120 envelope glyco-protein to its cell receptor (CD4) and a coreceptor (CXCR4 or CCR5), followed by a series of conformational changes in the gp41 transmembrane subunit ...

Induction of antibodies in rhesus macaques that recognize a fusion-intermediate conformation of HIV-1 gp41. [PDF]
A component to the problem of inducing broad neutralizing HIV-1 gp41 membrane proximal external region (MPER) antibodies is the need to focus the antibody response to the transiently exposed MPER pre-hairpin intermediate neutralization epitope.

Evolution of the HIV-1 envelope glycoproteins with a disulfide bond between gp120 and gp41 [PDF]
Background We previously described the construction of an HIV-1 envelope glycoprotein complex (Env) that is stabilized by an engineered intermolecular disulfide bond (SOS) between gp120 and gp41.

Nonneutralizing HIV-1 gp41 Envelope Cluster II Human Monoclonal Antibodies Show Polyreactivity for Binding to Phospholipids and Protein Autoantigens [PDF]
ABSTRACT HIV-1 gp41 envelope antibodies, which are frequently induced in HIV-1-infected individuals, are predominantly nonneutralizing. The rare and difficult-to-induce neutralizing antibodies (2F5 and 4E10) that target gp41 membrane-proximal epitopes (MPER) are polyspecific and require lipid binding for HIV-1 ...

Evaluation of cellular proteins binding to the transmembrane envelope protein gp41 of HIV-1 [PDF]
Das von HIV ausgelöste erwobene Immunschwäche-Syndrom (AIDS) stellt auch heute noch ein Problem dar. Im Jahr 2014 waren laut der Weltgesundheitsorganisation (WHO) 36,9 Millionen Menschen mit HIV infiziert. Heute, 30 Jahre nach der Entdeckung von HIV, gibt es zwar gute therapeutische Ansätze, eine Heilung ist aber bisher nicht in Aussicht.

The membrane-spanning domain of gp41 plays a critical role in intracellular trafficking of the HIV envelope protein [PDF]
AbstractBackgroundThe sequences of membrane-spanning domains (MSDs) on the gp41 subunit are highly conserved among many isolates of HIV-1. The GXXXG motif, a potential helix-helix interaction motif, and an arginine residue (rare in hydrophobic MSDs) are especially well conserved. These two conserved elements are expected to locate on the opposite sides
