    Summary
    Predicted to enable RNA binding activity; epidermal growth factor receptor binding activity; and protein C-terminus binding activity. Predicted to be involved in P-body assembly; negative regulation of receptor internalization; and stress granule assembly. Predicted to act upstream of or within several processes, including homeostasis of number of cells; neuromuscular process; and neuron differentiation. Predicted to be located in cytosol; perinuclear region of cytoplasm; and trans-Golgi network. Predicted to be part of polysome. Predicted to be active in cytoplasmic stress granule. Human ortholog(s) of this gene implicated in late onset Parkinson's disease and spinocerebellar ataxia type 2. Orthologous to human ATXN2 (ataxin 2).

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
