General annotation (Comments)
| Function | Involved in synapse maturation and required for normal muscle function. |
| Subunit structure | Interacts with dystrophin, utrophin and the syntrophins SNTA1, SNTB1, SNTB2, SNTG1 and SNTG2. Isoforms 5 and 6 do not interact with syntrophin. Isoforms 3 and 4 do not interact with utrophin. Binds dystrobrevin binding protein 1. Interacts with MAGEE1. Ref.6 Ref.7 Ref.8 Ref.9 |
| Subcellular location | Cytoplasm. Cell junction › synapse. Cell membrane. Note: In peripheral nerves, co-localizes with MAGEE1 in the Schwann cell membrane. Ref.9 |
| Tissue specificity | Expressed in skeletal muscle, heart, lung and brain. Sarcolemma and neuromuscular junction in skeletal muscle. Isoform 2 is restricted to the neuromuscular junction. Isoforms 5 and 6 are only expressed in muscle. |
| Developmental stage | Expression of alpha-dystrobrevin is up-regulated during differentiation, with isoforms 2, 5 and 6 expressed earliest and isoform 3 and 4 expressed later. |
| Domain | The coiled coil domain mediates the interaction with dystrophin and utrophin. |
| Post-translational modification | Phosphorylation of isoform 2 on tyrosine kinase substrate domain present in the C-terminus. |
| Sequence similarities | Belongs to the dystrophin family. Dystrobrevin subfamily. Contains 1 ZZ-type zinc finger. |
