trx | Histone-lysine N-methyltransferase trithorax; Histone methyltransferase that trimethylates 'Lys-9' of histone H3 (H3K9me3). H3 'Lys-9' methylation represents a specific tag for epigenetic transcriptional activation. Functions in segment determination through interaction with genes of bithorax (BX-C) and antennapedia (ANT-C) complexes. Acts as an activator of BX-C. Involved in the very early regulation of homeotic genes expressed only in the posterior region of the embryo. (3726 aa) | ||||
