Function
Histone demethylase that specifically demethylates 'Lys-9' of histone H3, thereby playing a central role in histone code. Preferentially demethylates mono- and dimethylated H3 'Lys-9' residue, with a preference for dimethylated residue, while it has weak or no activity on trimethylated H3 'Lys-9'. Demethylation of Lys residue generates formaldehyde and succinate. Involved in hormone-dependent transcriptional activation, by participating in recruitment to androgen-receptor target genes, resulting in H3 'Lys-9' demethylation and transcriptional activation. Involved in spermatogenesis by regulating expression of target genes such as PRM1 and TMP1 which are required for packaging and condensation of sperm chromatin. Involved in obesity resistance through regulation of metabolic genes such as PPARA and UCP1. -
Sequence similarities
Belongs to the JHDM2 histone demethylase family.
Contains 1 JmjC domain. -
Domain
The JmjC domain and the C6-type zinc-finger are required for the demethylation activity.
Leu-Xaa-Xaa-Leu-Leu (LXXLL) motifs are known to mediate the association with nuclear receptors. -
Cellular localization
Cytoplasm. Nucleus. Nuclear in round spermatids. When spermatids start to elongate, localizes to the cytoplasm where it forms distinct foci which disappear in mature spermatozoa. - Information by UniProt

Lanes 1 - 4: Merged signal (red and green). Green - ab191389 observed at 150 kDa. Red - loading control, ab18058, observed at 130 kDa.ab191389 was shown to specifically react with KDM3A when KDM3A knockout samples were used. Wild-type and KDM3A knockout samples were subjected to SDS-PAGE. Ab191389 and ab18058 (Mouse anti Vinculin loading control) were incubated overnight at 4°C at 500 dilution and 1/10000 dilution respectively. Blots were developed with 800CW Goat anti Rabbit and 680CW Goat anti Mouse secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
