    Summary
    Predicted to enable GTPase binding activity; double-stranded DNA binding activity; and ribonucleoprotein complex binding activity. Involved in alternative mRNA splicing, via spliceosome and neuron projection development. Acts upstream of or within regulation of dendrite morphogenesis. Located in cytoplasmic stress granule; neuronal ribonucleoprotein granule; and nuclear speck. Is expressed in several structures, including adrenal cortex; alimentary system; brain; eye; and skin. Used to study Renpenning syndrome. Human ortholog(s) of this gene implicated in Renpenning syndrome. Orthologous to human PQBP1 (polyglutamine binding protein 1).

    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.
