NTSR2 (Neurotensin Receptor 2): NTSR2 is a G protein-coupled receptor that binds neurotensin, a neurotransmitter involved in central nervous system functions such as pain relief, temperature regulation, and modulation of dopamine signaling. Activation of NTSR2 affects neural activity and has been associated with the pathophysiology of psychiatric disorders, making it a potential target for treatments in schizophrenia, mood disorders, and pain management.
