Target

  • Function

    Histone demethylase that specifically demethylates 'Lys-36' of histone H3, thereby playing a central role in histone code. Preferentially demethylates dimethylated H3 'Lys-36' residue while it has weak or no activity for mono- and tri-methylated H3 'Lys-36'. May also recognize and bind to some phosphorylated proteins and promote their ubiquitination and degradation. Required to maintain the heterochromatic state. Associates with centromeres and represses transcription of small non-coding RNAs that are encoded by the clusters of satellite repeats at the centromere. Required to sustain centromeric integrity and genomic stability, particularly during mitosis.

  • Tissue specificity

    Widely expressed, with highest levels in brain, testis and ovary, followed by lung.

  • Sequence similarities

    Belongs to the JHDM1 histone demethylase family.
    Contains 1 CXXC-type zinc finger.
    Contains 1 F-box domain.
    Contains 1 JmjC domain.
    Contains 6 LRR (leucine-rich) repeats.
    Contains 1 PHD-type zinc finger.

  • Domain

    The JmjC domain mediates demethylation activity and is required for satellite silencing.
    The CXXC zinc finger preferentially recognizes nonmethylated CpG DNA, and binding is blocked when the CpG DNA is methylated.

  • Post-translational
    modifications

    Phosphorylated upon DNA damage, probably by ATM or ATR.

  • Cellular localization

    Nucleus > nucleoplasm. Punctate expression throughout the nucleoplasm and enriched in the perinucleolar region. Specifically nucleates at CpG islands where it's presence results in chromatin depleted in H3K36me2.

      ab191387 was shown to specifically react with KDM2A in wild-type HAP1 cells. No band was observed when KDM2A knockout cells were examined. Wild-type and KDM2A knockout samples were subjected to SDS-PAGE. Ab191387 and ab9484 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1.313 ug/ml and 1/20,000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20,000 dilution for 1 hour at room temperature before imaging.
