Zahnow et al. investigate the evolution of epithelial sodium channels (ENaCs) in mammals returning to marine life. ENaCs are built of αβγ- or δβγ-subunits. Their study suggests the SCNN1D gene encoding the δ-subunit suffers pseudogenization events in marine mammals due to high-salinity environment.
