NPSR1 (Neuropeptide S Receptor 1): NPSR1 is a gene that encodes a G protein-coupled receptor for neuropeptide S, which plays a role in regulating arousal, anxiety, and other behavioural responses. It has been researched for its function in sleep-wake regulation and its potential effects on psychiatric disorders such as anxiety and panic disorder. Variations in NPSR1 are also associated with susceptibility to asthma and other inflammatory diseases, underscoring its wider importance in health and disease.
