Role of 'ectopic' olfactory receptors
Olfactory receptors in the nose are responsible for our perception of odours and also the perception of taste when we eat. Interestingly, olfactory receptors have also been found in various tissues including the heart, skin and brain in different animals including humans. However, their function is yet unclear.
Do zebrafish also express ectopic olfactory receptors?
What are they doing in other tissues?
