Is an ortholog of human SNTA1 (syntrophin alpha 1)\; SNTB1 (syntrophin beta 1)\; and SNTB2 (syntrophin beta 2). Exhibits acetylcholine transmembrane transporter activity and calcium channel regulator activity. Is involved in several processes, including acetylcholine transport\; muscle cell cellular homeostasis\; and negative regulation of ion transmembrane transporter activity. Localizes to the dystrophin-associated glycoprotein complex. Is expressed in the body wall musculature\; the nervous system\; and the vulval muscle. Is used to study Duchenne muscular dystrophy. Human ortholog(s) of this gene are implicated in long QT syndrome 12.
