An olfactory receptor is a G-protein coupled receptor, termed Golf, that detects odour by binding with odour molecules. There are around 1,000 genes associated with this process [1].

When there is stiumulant, through the nonhydrolyzable GTP analogue, it leads to the stiumulation of adenyly cyclase activity. Thus Golf  plays a role in olfactory signal transduction [2].
