The present invention relates to high-throughput mammalian and medium-throughput oocyte-based electrophysiological assays for identifying human TRPML3 modulators, preferably TRPML3 enhancers. Compounds that modulate TRPML3 function in the assay are expected to affect salty taste in humans. The inventive electrophysiological assays, such as the two-electrode voltage-clamp technique, facilitate the identification of compounds which specifically modulate human TRPML3.
