CHRNB3 (Cholinergic Receptor Nicotinic Beta 3 Subunit) is a protein that is part of the nicotinic acetylcholine receptor, which plays a crucial role in cholinergic neurotransmission. Variations in the CHRNB3 gene have been associated with nicotine dependence and related behavioral traits, indicating its involvement in the brain’s addiction pathways and regulation of neural circuits.
