Membrane biology: Membrane-regulated transcription
The activation of membrane-bound transcription factors involves release from the membrane by proteolysis. Recent studies show that, for some proteins, cleavage is performed by the proteasome, whereas others require specific proteases.
متن کاملMolecular Membrane Biology
GABAA receptors are the major inhibitory transmitter receptors in the central nervous system. They are chloride ion channels that can be opened by g-aminobutyric acid (GABA) and are the targets of action of a variety of pharmacologically and clinically important drugs. GABAA receptors are composed of five subunits that can belong to different subunit classes. The existence of 19 different subun...
متن کاملExcitation in Plant Membrane Biology
Very few substances can waltz right through cell membranes-indeed, could they do so, cells would lose their integrity rapidly. The control of ion and macromolecule passage through both plasma membranes and organellar membranes falls to various channel, pump, and carrier proteins, which are diagrammed in Figure 1. Not onlydo these proteins allow ions and other macromolecules to pass from one sid...
متن کاملMembrane Biology: Fission behind BARs
Membrane bending is accomplished in part by amphipathic helix insertion into the bilayer and the assembly of BAR domain scaffolds preparing the membrane for fission. Two recent studies highlight the roles of amphipathic helices and BAR scaffolds in membrane fission and establish the structural basis of membrane bending by the N-BAR protein endophilin.
