  • 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Ubiquitous.
  • 序列相似性Belongs to the JHDM3 histone demethylase family.
    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
    Whole cell lysates derived from 293T transfected with Flag-KDM4A were prepared using PBS+1% Triton plus proteinase inhibitor cocktail.
  • The antibody (1/1000 dilution) was tested for IP of KDM4A in HeLa nuclear extracts under three different conditions: 1) regular (25 mM Tris, pH 7.6, 150 mM KCl, 0.1% NP40, 0.5 mM EDTA, 1 mM DTT; 2) ChIP without SDS (ChIP solution C with 1% Triton and 0.1% deoxycholine); 3) ChIP buffer (as 2 plus 0.1% SDS). 10% input is seen upon longer exposure. SDS presence in this case inhibits IP.
  • Overlay histogram showing HeLa cells stained with ab105953 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab105953, 0.5µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG (1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
