    Summary
    Predicted to enable several functions, including histone methyltransferase binding activity; identical protein binding activity; and methylated histone binding activity. Predicted to be involved in cellular response to DNA damage stimulus; chromatin organization; and negative regulation of transcription by RNA polymerase II. Predicted to act upstream of or within negative regulation of transcription, DNA-templated. Predicted to be located in several cellular components, including chromocenter; chromosome; and pronucleus. Predicted to be active in pericentric heterochromatin. Predicted to colocalize with chromosome, telomeric region. Orthologous to human CBX1 (chromobox 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.
