NTSR2 (Neurotensin Receptor 2): NTSR2 is a G protein-coupled receptor that binds neurotensin, a neurotransmitter involved in central nervous system functions such as analgesia, thermoregulation, and modulation of dopamine signaling. Activation of NTSR2 influences neural activity and has been linked to the pathophysiology of psychiatric disorders, making it a potential target for therapies in schizophrenia, mood disorders, and pain management.
