NPSR1 (Neuropeptide S Receptor 1): NPSR1 is a gene that encodes a G protein-coupled receptor for neuropeptide S, involved in regulating arousal, anxiety, and other behavioral responses. It has been studied for its role in sleep-wake regulation and its potential impact on psychiatric conditions such as anxiety and panic disorder. Variations in NPSR1 are also linked to susceptibility to asthma and other inflammatory diseases, highlighting its broader significance in health and disease.
