Automated description from the Alliance of Genome Resources
Predicted to have GTPase binding activity and ankyrin binding activity. Involved in common-partner SMAD protein phosphorylation; protein localization to plasma membrane; and regulation of SMAD protein signal transduction. Localizes to several cellular components, including the M band; axolemma; and cuticular plate. Used to study Beckwith-Wiedemann syndrome. Is expressed in several structures, including brain; liver; sciatic nerve; spinal cord; and spleen. Orthologous to human SPTBN1 (spectrin beta, non-erythrocytic 1).
