Gene: ATXN2 (ataxin 2) Homo sapiens
Symbol: ATXN2
Name: ataxin 2
Description: Exhibits epidermal growth factor receptor binding activity and protein C-terminus binding activity. Involved in cytoplasmic mRNA processing body assembly; negative regulation of receptor internalization; and stress granule assembly. Localizes to several cellular components, including cytoplasmic stress granule; polysome; and trans-Golgi network. Implicated in late onset Parkinson's disease and spinocerebellar ataxia type 2.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: ASL13; ataxin-2; ATX2; FLJ46772; SCA2; spinocerebellar ataxia type 2 protein; TNRC13; trinucleotide repeat containing 13; trinucleotide repeat-containing gene 13 protein
