A molecular structure-function investigation of major membrane channels involved in olfactory transduction. Olfactory receptor neurons are extraordinarily-sensitive sensors for detecting minute concentrations of odorant molecules. This project aims to extend our previous studies of these specialised mammalian olfactory cells by using state-of-the art technologies: electrophysiology (patch-clamp) and molecular biology (site-directed-mutagenesis), to investigate how the molecular structure of the ....A molecular structure-function investigation of major membrane channels involved in olfactory transduction. Olfactory receptor neurons are extraordinarily-sensitive sensors for detecting minute concentrations of odorant molecules. This project aims to extend our previous studies of these specialised mammalian olfactory cells by using state-of-the art technologies: electrophysiology (patch-clamp) and molecular biology (site-directed-mutagenesis), to investigate how the molecular structure of their ion channels (selective protein pores) and receptors contribute to the odorant-induced generation of electrical activity, which mediates our sense of smell (olfaction). The project has specific relevance for understanding olfaction, as well as relevance for other sensory systems and other ion channels.Read moreRead less
