    Summary
    Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity; actin filament binding activity; and actin monomer binding activity. Acts upstream of or within regulation of transcription by RNA polymerase II. Located in cytoplasm; cytoskeleton; and nucleus. Is expressed in several structures, including alimentary system; central nervous system; embryo mesenchyme; genitourinary system; and sensory organ. Human ortholog(s) of this gene implicated in alcohol dependence. Orthologous to human PKNOX2 (PBX/knotted 1 homeobox 2). [provided by Alliance of Genome Resources, Dec 2024]

    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.
