Protein
Neuronal acetylcholine receptor subunit alpha-2
Gene
CHRNA2
Organism
Pan troglodytes (Chimpanzee)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at transcript leveli

Functioni

After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane By similarity.

    Interactioni

    Subunit structurei

    Neuronal AChR seems to be composed of two different types of subunits: alpha and non-alpha (beta). Alpha-2 subunit can be combined to beta-2 or beta-4 to give rise to functional receptors By similarity.
