This family contains a number of hypothetical bacterial proteins of unknown function approximately 200 residues long. This region is is distantly similar to other PAS domains.
","llm":false,"checked":false,"updated":false}],"wikipedia":[{"title":"PAS_domain","extract":"A Per-Arnt-Sim (PAS) domain is a protein domain found in all kingdoms of life. Generally, the PAS domain acts as a molecular sensor, whereby small molecules and other proteins associate via binding of the PAS domain. 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.
