Dopamine receptors are a type of G protein-coupled receptor that bind the neurotransmitter dopamine. These receptors play a key role in regulating various physiological functions, including movement, cognition, motivation, and reward. Dysfunction of dopamine receptors has been implicated in various neurological and psychiatric disorders, such as Parkinson's disease, schizophrenia, and addiction. Research in this area aims to better understand the structure and function of dopamine receptors, as well as develop new therapeutic agents targeting these receptors for the treatment of related disorders.
