Automated description from the Alliance of Genome Resources (Release 7.2.0)
Enables actin binding activity; ankyrin binding activity; and spectrin binding activity. Involved in clustering of voltage-gated sodium channels and protein localization to plasma membrane. Acts upstream of or within several processes, including adult walking behavior; regulation of heart contraction; and regulation of peptidyl-serine phosphorylation. Located in several cellular components, including axon; cell body fiber; and intercalated disc. Is active in juxtaparanode region of axon. 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).
