During activation of HOXB3 by retimoic acid in fibroblasts (Lan et al. 2007) and embryonal carcinoma cells (Lee et al. 2007) chromatin at HOXB3 loses methylation at lysine-27 of histone H3 (H3K27me3), loses PRC2, and gains methylation at H3K4. The demethylase KDM6A (UTX) binds HOXB3 chromatin during activation (Lan et al. 2007, Lee et al. 2007) and may participate in demethylating H3K27me3. KDM6A forms complexes with the histone methyltransferases KMT2C,D (MLL2,3) which may participate in methylating H3K4 (Lee et al. 2007)
