The PAS domain is a protein domain contained in many signaling proteins where it functions as a signal sensor. PAS domains are found in a large number of organisms from bacteria to humans. The PAS domain was named after the three proteins in which it was first discovered:
- Per – period circadian protein
- Arnt – aryl hydrocarbon receptor nuclear translocator protein
- Sim – single-minded protein
B. subtilis proteins containing a PAS domain
