Nicotinic Acetylcholine Receptor Alpha 4 Subunit is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
CHRNA4 encodes the alpha 4 subunit of neuronal nicotinic acetylcholine receptors. The α4β2 nAChR is the most abundant nicotinic receptor in the brain, while α4α5β2 receptors are expressed in dopamine-rich regions. These receptors mediate fast excitatory neurotransmission and modulate release of dopamine, GABA, and glutamate[1].
The CHRNA4 protein (627 amino acids) is a ligand-gated ion channel subunit:
CHRNA4 shows widespread brain expression:
CHRNA4-containing receptors are drug targets:
