This hormone is produced in the brainbrain in humans during puberty and controls most of the processes associated with sexual differentiation and the development of reproductive functions. The study showed that the development of this hormone and receptors susceptible to it must go back to Bilateria, a common ancestor of humans and invertebrate species that lived more than half a billion years ago.
Moreover, unlike people who haveonly one kisseptin receptor, in starfish (Asterias rubens) researchers have discovered a whole network of receptors that perceive this or similar hormones in structure. In this species, eleven genes have been found encoding kisseptin and four genes responsible for molecules that are similar in their properties, which can also act on the receptors of this hormone.
At the same time, the researchers found that the functionscontrolled by kisseptin are significantly different in starfish. The full spectrum of all reactions is not yet known, but it has already been shown that molecules similar to kisseptin cause a reaction in starfish that leads to vomiting.
The researchers believe that a better understanding of the evolution of various processes in the human body will help determine the causes of associated impairments, alternate functions, and side effects.
