Did you know?
hERG (the human Ether-à-go-go-Related Gene) is a gene (KCNH2) that codes for a protein known as Kv11.1, the alpha subunit of a potassium ion channel. This ion channel (sometimes simply denoted as 'hERG') is best known for its contribution to the electrical activity of the heart: the hERG channel … Zobacz więcej hERG forms the major portion of one of the ion channel proteins (the 'rapid' delayed rectifier current (IKr)) that conducts potassium (K ) ions out of the muscle cells of the heart (cardiac myocytes), … Zobacz więcej A detailed atomic structure for hERG based on X-ray crystallography is not yet available, but structures have recently been solved by … Zobacz więcej This channel is also sensitive to drug binding, as well as decreased extracellular potassium levels, both of which can result in decreased channel function and drug-induced (acquired) long QT syndrome. Among the drugs that can cause QT prolongation, … Zobacz więcej HERG has been shown to interact with the 14-3-3 epsilon protein, encoded by YWHAE. Zobacz więcej Loss-of-function mutations in this channel may lead to long QT syndrome (LQT2), while gain-of-function mutations may lead to short QT syndrome. Both clinical disorders stem … Zobacz więcej Due to the documented potential of QT-interval-prolonging drugs, the United States Food and Drug Administration issued … Zobacz więcej The hERG gene was first named and described in a paper by Jeff Warmke and Barry Ganetzky, then both at the University of Wisconsin–Madison. The hERG gene is the human … Zobacz więcej WitrynaThe human ether-a-go-go-related gene (hERG) ...

Witryna4 lis 2024 · Since hERG patch clamp assays are typically run at sub-physiological gating frequencies (and gating is neglected altogether in radio-ligand binding assays), this hijacking effect is likely underestimated to varying degrees (i.e. channel closing likely dominates over the re-solvation costs of the dissociated pore and blocker). WitrynaTo address the need for an inexpensive, rapid, and comprehensive assay to predict both types of hERG risk early in the drug development process, we have developed a …
Witryna1 lip 2012 · The human ether-a-go-go related gene (hERG) encodes the pore-forming subunit of the rapid component of the delayed rectifier K+ channel, Kv11.1, which are expressed in the heart, various brain regions, smooth muscle cells, endocrine cells, and a wide range of tumor cell lines. However, it is the role that Kv11.1 channels play in the … WitrynahERG (the human Ether-à-go-go-Related Gene)，人延迟整流钾离子通道基因，是指基因KCNH2。 该基因编码的蛋白质被称为 K v 11.1，是钾离子通道(英語： potassium ion channel)的α亚基（英語： alpha subunit ）。 该基因编码的钾离子通道（有时简单地使用'hERG'表示）最为著名的是其对心脏的电位活性，可协调心跳（即 ...
