An evidence for a potassium channel in endoplasmic reticulum based on single channel recording in bilayer lipid membrane
Introduction Numerous studies have demonstrated the presence of potassium selective channels in membranes internal organelles. These channels are essential to a large variety of cellular processes including intracellular 2+ a signaling, protein recycling, charge neutralization and cell protection. In contrast to the sarcoplasmic reticulum + here potassium channels have been clearly ...

متن کاملIntegration of membrane proteins into the endoplasmic reticulum requires GTP
We have examined the requirement for ribonucleotides and ribonucleotide triphosphate hydrolysis during early events in the membrane integration of two membrane proteins: the G protein of vesicular stomatitis virus and the hemagglutinin-neuraminidase (HN) glycoprotein of Newcastle disease virus. Both proteins contain a single transmembrane-spanning segment but are integrated in the membrane with...
متن کاملThe unfolded protein response coordinates the production of endoplasmic reticulum protein and endoplasmic reticulum membrane.
The endoplasmic reticulum (ER) is a multifunctional organelle responsible for production of both lumenal and membrane components of secretory pathway compartments. Secretory proteins are folded, processed, and sorted in the ER lumen and lipid synthesis occurs on the ER membrane itself. In the yeast Saccharomyces cerevisiae, synthesis of ER components is highly regulated: the ER-resident protein...
متن کاملCoxsackievirus protein 2B modifies endoplasmic reticulum membrane and plasma membrane permeability and facilitates virus release.
Digital-imaging microscopy was performed to study the effect of Coxsackie B3 virus infection on the cytosolic free Ca2+ concentration and the Ca2+ content of the endoplasmic reticulum (ER). During the course of infection a gradual increase in the cytosolic free Ca2+ concentration was observed, due to the influx of extracellular Ca2+. The Ca2+ content of the ER decreased in time with kinetics in...
