WebMar 1, 2013 · Pheromones are recognized by specific receptors expressed on the surface of cells of the opposite mating type and this binding stimulates the activation of receptor-associated heterotrimeric G-proteins, which in turn promote the activation of a conserved mitogen-activated protein kinase (MAPK) module. WebSep 15, 2015 · Pheromone receptor genes constitute a specialized olfactory receptor subfamily that shares sequence homology. In most cases the pheromone receptor genes are more abundantly expressed in male antennae, and the expression is confined to the neurons in the long sensilla trichodea, which are responsible for pheromone sensing.

WebPheromones differ from sight or sound signals in a number of ways. They travel slowly, do not fade quickly, and are effective over a long range. Sound and sight receptors are not needed for pheromone detection, and pheromone direction is not limited to straight lines. Examples of pheromone use by insects and spiders.
