Investigating cardiotoxicity related with hERG channel blockers …
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 mediates … 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 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 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 recommendations for the establishment of a cardiac safety profile during pre-clinical drug development: ICH S7B. The … Zobacz więcej HERG has been shown to interact with the 14-3-3 epsilon protein, encoded by YWHAE.
