When synapse building blocks became scarce: Bayreuth biologists explain protein exchange during vertebrate evolution

The electrical synapses in vertebrates are made of different, but by no means more powerful proteins than the electrical synapses in far older invertebrates. Animal physiologists at the University of Bayreuth have now found an explanation for this evolutionary puzzle. In the early phase of vertebrate evolution, there was a loss of diversity in precisely those proteins that had been used for signal transmission in older invertebrates. The scientists have published their discovery in the journal eLife.
