Protein Coding Gene : Sptbn4 spectrin beta, non-erythrocytic 4

Primary Identifier  MGI:1890574 Organism  mouse, laboratory
Chromosome  7 NCBI Gene Number  80297
Mgi Type  protein coding gene
description  FUNCTION: Automated description from the Alliance of Genome Resources (Release 8.0.0)

Enables actin binding activity and spectrin binding activity. Involved in protein localization. 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 liver; 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]
