Previous Symbols for SPTBN2 Gene
Spectrins are principle components of a cell's membrane-cytoskeleton and are composed of two alpha and two beta spectrin subunits. The protein encoded by this gene (SPTBN2), is called spectrin beta non-erythrocytic 2 or beta-III spectrin. It is related to, but distinct from, the beta-II spectrin gene which is also known as spectrin beta non-erythrocytic 1 (SPTBN1). SPTBN2 regulates the glutamate signaling pathway by stabilizing the glutamate transporter EAAT4 at the surface of the plasma membrane. Mutations in this gene cause a form of spinocerebellar ataxia, SCA5, that is characterized by neurodegeneration, progressive locomotor incoordination, dysarthria, and uncoordinated eye movements.

GeneCards Summary for SPTBN2 Gene
SPTBN2 (Spectrin, Beta, Non-Erythrocytic 2) is a Protein Coding gene. Diseases associated with SPTBN2 include spinocerebellar ataxia 5 and spectrin-associated autosomal recessive cerebellar ataxia. Among its related pathways are Class I MHC mediated antigen processing and presentation and L1CAM interactions. GO annotations related to this gene include phospholipid binding and structural constituent of cytoskeleton. An important paralog of this gene is ACTN2.
