Automated description from the Alliance of Genome Resources (Release 3.2)
Exhibits actin binding activity; ankyrin binding activity; and spectrin binding activity. Involved in several processes, including adult walking behavior; neuron development; and regulation of heart contraction. Localizes to several cellular components, including axon; cell body fiber; and intercalated disc. Colocalizes with adherens junction. Is expressed in several structures, including liver; neural ectoderm; optic vesicle; spinal cord lateral wall; and spleen. Orthologous to human SPTBN4 (spectrin beta, non-erythrocytic 4).
