Used in neuroscience research to study pain modulation and the central nervous system’s response to stress and anxiety. Acts as a fragment of the full nociceptin peptide, helping investigate receptor binding and signaling mechanisms without inducing full receptor activation. Applied in studies related to addiction, mood disorders, and regulation of emotional behavior due to its role in the nociceptin opioid peptide receptor system. Also utilized in developing potential therapeutic agents targeting anxiety, depression, and substance abuse.
