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 behavioral responses. It has been studied for its involvement in sleep-wake cycles and its potential effects on psychiatric conditions such as anxiety and panic disorder. Variations in NPSR1 are also associated with susceptibility to asthma and other inflammatory diseases, underscoring its broader importance in health and disease.
