WitrynaHERG mutations often disrupt the forward trafficking of hERG (thereby reducing sarcolemmal expression of the channel), and subsequently result in decreased I Kr (Anderson et al., 2006). The hERG channel is also a notorious target for several classes of drugs that engender acquired long QT syndrome (LQTS) (Sanguinetti and Tristani … Witryna11 lut 2024 · Wible et al. showed that up to 40% of the hERG blockers evaluated also inhibited hERG protein trafficking in cardiac cells; but most importantly, approximately 6% of non-hERG blockers specifically altered hERG trafficking.
