PAS domain

Introduction

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
