  • Function

    May be involved in the formation and stability of synapses as well as being involved in the clustering of nicotinic acetylcholine receptors.
  • Tissue specificity

    Highly expressed in brain, skeletal and cardiac muscles, and expressed at lower levels in lung, liver and pancreas. Isoform 2 is not expressed in cardiac muscle. Isoform 7 and isoform 8 are only expressed in muscle.
  • Involvement in disease

    Defects in DTNA are the cause of left ventricular non-compaction type 1 (LVNC1) [MIM:604169]. Left ventricular non-compaction is due to an arrest of myocardial morphogenesis. The disorder is characterized by a hypertrophic left ventricule with deep trabeculations and with poor systolic function, with or without associated left ventricular dilation. In some cases, it is associated with other congenital heart anomalies such as ventricular septal defects, pulmonic stenosis and atrial septal defects. The right ventricle may also be affected.
  • Sequence similarities

    Belongs to the dystrophin family. Dystrobrevin subfamily.
    Contains 1 ZZ-type zinc finger.
  • Domain

    The coiled coil domain mediates the interaction with dystrophin and utrophin.
  • Post-translational

    Phosphorylation of DTN-1 on tyrosine kinase substrate domain present in the C-terminus.
  • Cellular localization

    Cytoplasm. Cell junction > synapse. Cell membrane. In peripheral nerves, co-localizes with MAGEE1 in the Schwann cell membrane.
