Lysine-specific demethylase 6A (KDM6A)

Histone demethylase that specifically demethylates'Lys- 27' of histone H3, thereby playing a central role in histone code (PubMed:17851529, PubMed:17713478, PubMed:17761849). Demethylates trimethylated and dimethylated although not monomethylated H3'Lys-27' (PubMed:17851529, PubMed:17713478, PubMed:17761849).

Plays a central role in regulation of posterior development, by regulating HOX gene expression (PubMed:17851529). Demethylation of 'Lys-27' of histone H3 is concomitant with methylation of 'Lys-4' of histone H3, and regulates the recruitment of the PRC1 complex and monoubiquitination of histone H2A (PubMed:17761849).
