Our new paper with lead and corresponding author Luis Yañez-Guerra on placozoan monoamine GPCRs and the "Prebilaterian origin of monoaminergic signaling" […] [Original post on biologists.social]

- Non-bilaterian placozoans produce, detect, and behaviorally respond to monoamines
•
Five placozoan GPCRs are activated by monoamines
•
Four placozoan receptors are homologous to human melatonin receptors
•
Placozoans reveal the pre-bilaterian origin of monoaminergic signaling
