Membrane Thinning and Thickening Induced by Membrane-Active Amphipathic Peptides
Membrane thinning has been discussed as a fundamental mechanism by which antimicrobial peptides can perturb cellular membranes. To understand which factors play a role in this process, we compared several amphipathic peptides with different structures, sizes and functions in their influence on the lipid bilayer thickness. PGLa and magainin 2 from X. laevis were studied as typical representative...
متن کاملRotavirus Disrupts Calcium Homeostasis by NSP4 Viroporin Activity
Many viruses alter intracellular calcium homeostasis. The rotavirus nonstructural protein 4 (NSP4), an endoplasmic reticulum (ER) transmembrane glycoprotein, increases intracellular levels of cytoplasmic Ca(2+) ([Ca(2+)]cyto) through a phospholipase C-independent pathway, which is required for virus replication and morphogenesis. However, the NSP4 domain and mechanism that increases [Ca(2+)]cyt...
متن کاملAnisotropic Membrane Curvature Sensing by Amphipathic Peptides.
Many proteins and peptides have an intrinsic capacity to sense and induce membrane curvature, and play crucial roles for organizing and remodeling cell membranes. However, the molecular driving forces behind these processes are not well understood. Here, we describe an approach to study curvature sensing by simulating the interactions of single molecules with a buckled lipid bilayer. We analyze...
متن کاملDimerization of Tie2 mediated by its membrane-proximal FNIII domains.
Tie1 and Tie2, members of the tyrosine kinase family with immunoglobulin and EGF homology domains, are receptor tyrosine kinases found primarily in endothelial cells with key roles in development and maintenance of the vasculature and in angiogenesis. They are attractive targets for therapeutic intervention in tumor angiogenesis, inflammation, and sepsis. Tie2 is regulated directly by the multi...
متن کاملAntiviral Activity of Arnebia Euchroma and Amniotic Membrane against HSV-1, Rotavirus, and Influenza Virus
Background and Aims: Currently, there are antiviral chemicals used to treat viral infections accompanied by limitations such as high levels of toxicity and adverse effects in humans, the emergence of drug-resistant viral strains, low numbers, and limited diversity. Therefore, it is necessary to evaluate new photochemical to obtain new therapeutic methods. The present study was conducted to eval...
