Functional evolution of Erg potassium channel gating reveals an ancient origin for I Kr
Open accessAbstract
Significance: Ether-a-go-go related gene (Erg) family K + channels regulate excitability of muscle and neurons. However, mammalian and Drosophila Erg channels have distinctive gating phenotypes, suggesting divergent physiological roles. We examined the origins of Erg channel gating properties by investigating the functional evolution of the Erg family in Eumetazoa. We find that the mammalian I Kr -like Erg channel phenotype is ancestral. Thus, the gating features that specialize Erg1 for cardiac action potential repolarization may have had their origins in the slow wave contractions of early metazoans. These gating features, inactivation and slow deactivation, have been lost in the Drosophila Erg, Caenorhabditis elegans Erg, and some sea anemone ( Nematostella ) Ergs. Loss of the Ether-a-go-go domain, which regulates channel closing, accompanies and may in part explain phenotypic conversion.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
