| Mgi Type | protein coding gene |
| description | FUNCTION: Automated description from the Alliance of Genome Resources (Release 9.1.0) Enables actin binding activity and spectrin binding activity. Acts upstream of or within several processes, including adult walking behavior; neuron development; and regulation of heart contraction. Located in axon; cell body fiber; and intercalated disc. Is active in juxtaparanode region of axon and node of Ranvier. Is expressed in several structures, including cochlea; neural ectoderm; optic vesicle; spinal cord lateral wall; and spleen. Orthologous to human SPTBN4 (spectrin beta, non-erythrocytic 4). PHENOTYPE: Homozygotes for spontaneous mutations exhibit tremors, progressive ataxia with hind limb paralysis, central deafness, reduced body weight, and shortened lifespan. Males are sterile, but females may breed. [provided by MGI curators] |
