  • 靶标

    • 功能
      Histone demethylase that specifically demethylates 'Lys-9' and 'Lys-36' residues of histone H3, thereby playing a central role in histone code. Does not demethylate histone H3 'Lys-4', H3 'Lys-27' nor H4 'Lys-20'. Demethylates trimethylated H3 'Lys-9' and H3 'Lys-36' residue, while it has no activity on mono- and dimethylated residues. Demethylation of Lys residue generates formaldehyde and succinate. Participates in transcriptional repression of ASCL2 and E2F-responsive promoters via the recruitment of histone deacetylases and NCOR1, respectively.
      Isoform 2: Crucial for muscle differentiation, promotes transcriptional activation of the Myog gene by directing the removal of repressive chromatin marks at its promoter. Lacks the N-terminal demethylase domain.
    • 组织特异性
    • 序列相似性
      Belongs to the JHDM3 histone demethylase family.
      Contains 1 C2HC pre-PHD-type zinc finger.
      Contains 1 JmjC domain.
      Contains 1 JmjN domain.
      Contains 2 PHD-type zinc fingers.
      Contains 2 Tudor domains.
    • 结构域
      The 2 Tudor domains recognize and bind methylated histone H3 'Lys-4' residue (H3K4me). Double Tudor domain has an interdigitated structure and the unusual fold is required for its ability to bind methylated histone tails. Trimethylated H3 'Lys-4' (H3K4me3) is bound in a cage of 3 aromatic residues, 2 of which are from the Tudor domain 2, while the binding specificity is determined by side-chain interactions involving residues from the Tudor domain 1. The Tudor domains are also able to bind trimethylated histone H3 'Lys-9' (H3K9me3), di- and trimethylated H4 'Lys-20' (H4K20me2 and H4K20me3). Has high affinity for H4K20me2, blocking recruitment of proteins such as TP53BP1.
    • 翻译后修饰
      Ubiquitinated by RNF8 and RNF168 following DNA damage, leading to its degradation. Degradation promotes accessibility of H4K20me2 mark for DNA repair protein TP53BP1, which is then recruited.

      Predicted band size: 121 kDa
      Observed band size: 130 kDa (why is the actual band size different from the predicted?)
      Additional bands at: 100 kDa. We are unsure as to the identity of these extra bands.

    • Detection of Human KDM4A / JHDM3A / JMJD2A by Immunoprecipitation in Whole cell lysate from HeLa cells (1 mg for IP, 20% of IP loaded), using ab70786 at 3 µg/mg lysate (Lane 1). Lane 2 represents IgG IP control. Subsequent Western blot detection of KDM4A / JHDM3A / JMJD2A was performed using ab70786 at 1 µg/ml.
