1 Importantly, desipramine belongs to a group of tricyclic antidepressant compounds that can simultaneously block hERG and inhibit its surface expression. Desipramine ETS transcription factor ERG Homo sapiens
2 Here, we have studied in detail how desipramine inhibits hERG surface expression. Desipramine ETS transcription factor ERG Homo sapiens
3 We find a previously unrecognized combination of two entirely different mechanisms; desipramine increases hERG endocytosis and degradation as a consequence of drug-induced channel ubiquitination and simultaneously inhibits hERG forward trafficking from the endoplasmic reticulum. Desipramine ETS transcription factor ERG Homo sapiens
4 We find a previously unrecognized combination of two entirely different mechanisms; desipramine increases hERG endocytosis and degradation as a consequence of drug-induced channel ubiquitination and simultaneously inhibits hERG forward trafficking from the endoplasmic reticulum.
