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) | ||||
Pxt | Chorion peroxidase; Peroxinectin-like (Pxt) encodes a cycloxygenase-like enzyme that contributes to the synthesis of prostaglandins. Prostaglandins activate G protein-coupled receptor signaling. Its roles include oogenesis, sperm individualization, morphogenesis, nucleolar structure, temporal control of gene expression, and regulation of gene amplification; Belongs to the peroxidase family. XPO subfamily. (809 aa) |
