Signal transduction and perception regulates biological activities to adapt to changing environments. The Pert-Arnt-Sim domains are commonly available sensors found across diverse receptors in bacteria, eukaryotes, and archaea. However, the extent of their functional diversity and their distribution across the tree of life remains to be characterized.
