Protein

Acetylcholine receptor subunit beta

Gene

Chrnb1

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -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.

Interactioni

Subunit structurei

Pentamer of two alpha chains, and one each of the beta, delta, and gamma (in immature muscle) or epsilon (in mature muscle) chains. The muscle heteropentamer composed of alpha-1, beta-1, delta, epsilon subunits interacts with the alpha-conotoxin ImII.By similarity
