CHRND

Acetylcholine receptor subunit delta is a protein that in humans is encoded by the CHRND gene.

Function
The acetylcholine receptor of muscle has 5 subunits of 4 different types: 2 alpha and 1 each of beta, gamma and delta subunits. After acetylcholine binding, the receptor undergoes an extensive conformation change that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane.

Interactions
CHRND has been shown to interact with Cholinergic receptor, nicotinic, alpha 1.

Clinical significance
Mutations in CHRND are known to cause the following conditions:


 * Multiple pterygium syndrome, lethal type (LMPS);
 * Myasthenic syndrome, congenital, 3A, slow-channel (CMS3A);
 * Myasthenic syndrome, congenital, 3B, fast-channel (CMS3B);
 * Myasthenic syndrome, congenital, 3C, associated with acetylcholine receptor deficiency (CMS3C).
