Summary: Enables acetylcholine transmembrane transporter activity and cytoskeletal protein binding activity. Involved in several processes, including muscle cell cellular homeostasis; positive regulation of cholinergic synaptic transmission; and sarcomere organization. Located in plasma membrane. Part of dystrobrevin complex. Is expressed in several structures, including body wall musculature; dorsal nerve cord; intestinal cell; neurons; and non-striated muscle. Used to study Duchenne muscular dystrophy. Human ortholog(s) of this gene implicated in cardiomyopathy and left ventricular noncompaction. Orthologous to several human genes including DTNA (dystrobrevin alpha). [provided by Alliance of Genome Resources, Jan 2025]

What's a GeneRIF?

SLO-1 potassium channels distinctively form organized clusters at presynaptic terminals; two cytoskeletal proteins, CTN-1 and DYB-1, are crucial for normal SLO-1 cluster formation
Title: Presynaptic BK channel localization is dependent on the hierarchical organization of alpha-catulin and dystrobrevin and fine-tuned by CaV2 calcium channels.
the interaction between alpha-catulin and alpha-dystrobrevin is evolutionarily conserved in C. elegans and mouse muscles and strongly suggests that this interaction contributes to the integrity of the dystrophin complex
Title: Interaction of α-catulin with dystrobrevin contributes to integrity of dystrophin complex in muscle.
These observations revealed novel functions of dystrobrevin in controlling neurotransmitter release and muscle Ca(2+) transients by localizing the BK channel.
