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 proteinMany PAS-domain proteins detect their signal by way of an associated cofactor such as heme.
