A Per-Arnt-Sim (PAS) domain is a protein domain found in all kingdoms of life.[2] Generally, the PAS domain acts as a molecular sensor, whereby small molecules and other proteins associate via binding of the PAS domain.[3][4][5] Due to this sensing capability, the PAS domain has been shown as the key structural motif involved in protein-protein interactions of the circadian clock, and it is also a common motif found in signaling proteins, where it functions as a signaling sensor.[6][7]
