hERG - Wikipedia
hERG (the human Ether-à-go-go-Related Gene) is a gene that codes for a protein known as K v 11.1, 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 mediates the repolarizing I Kr current in the cardiac ...

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,hERG通道介导在心脏动作电位中 延迟整流钾电流--I Kr 的复极化)。
hERG K(+) channels: structure, function, and clinical significance
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.

The hERG K + channel: target and antitarget strategies in drug development
2008年3月1日 · The human ether-à-go-go related gene (hERG) K + channel is of great interest for both basic researchers and clinicians because its blockade by drugs can lead to QT prolongation, which is a risk factor for torsades de pointes, a potentially life-threatening arrhythmia. A growing list of agents with “QT liability” have been withdrawn from ...
