From viruses to humans - Exploring the structure-function relationship of the Kesv protein for the future of biomedicine

Abstract

Viruses often use ion channel proteins to initialise host infections. Defects in ion channel proteins are also linked to several metabolic disorders in humans. In that instance, modulation of ion channel activities becomes central to development of antiviral therapies and drug design. Kesv, a potassium-selective ion channel protein expressed by Ectocarpus siliculosus virus (EsV), possesses remarkable properties which can help to characterise the molecular basis of the functional processes relevant to virus biology and human physiology. The small structural features of this ion channel could serve as a fundamental primer to study more complex ion channels from humans. Therefore, in spite of their evolutionary distance, the potential link between viral and human ion channel proteins could provide opportunities for therapeutic and biotechnological applications.
