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) | ||||
mmy | Mummy, isoform A; Mummy (mmy) encodes an UDP-N-acetylglucosamine diphosphorylase. It functions in apical extracellular matrix formation by producing GlcNAc residues needed for chitin synthesis and protein glycosylation. It regulates cuticle production, tracheal morphogenesis, and axon guidance. (520 aa) |
