Automated description from the Alliance of Genome Resources (Release 7.0.0)
Predicted to enable GTPase binding activity; actin filament binding activity; and ankyrin binding activity. Predicted to be a structural constituent of cytoskeleton. Involved in central nervous system formation and protein localization to plasma membrane. Acts upstream of or within regulation of SMAD protein signal transduction. Located in several cellular components, including M band; axolemma; and cuticular plate. Is expressed in several structures, including brain; liver; sciatic nerve; spinal cord; and spleen. Used to study Beckwith-Wiedemann syndrome. Orthologous to human SPTBN1 (spectrin beta, non-erythrocytic 1).
