Gustducin is the most common taste Gα subunit, having a major role in TAS2R bitter taste reception.

She and her collaborator Dr. Joseph Brand concluded that modern cats have lost function in an obsolete taste receptor, removing the ability to taste sweets, unlike their prehistoric ancestors.
However, the receptor-independent process involves the diffusion of bitter, amphiphilic chemicals like quinine across the taste receptor cell membranes.
