Euplotes raikovi mating pheromone
This family consists of several Euplotes raikovi mating pheromone proteins. Diffusible polypeptide pheromones, which distinguish otherwise morphologically identical vegetative cell types from one another, are produced by some species of ciliates. In the marine sand-dwelling protozoan ciliate Euplotes raikovi, pheromone molecules promote the vegetative reproduction (mitogenic proliferation or growth) of the same cells from which they originate. As, understandably, such autocrine pheromone activity is primary to that of targeting and inducing a foreign cell to mate (paracrine functions), this finding provides an example of how the original function of a molecule can be obscured during evolution by the acquisition of a new one.
