E(z) | Histone-lysine N-methyltransferase E(z); Polycomb group (PcG) protein. Catalytic subunit of the Esc/E(z) complex, which methylates 'Lys-9' and 'Lys-27' of histone H3, leading to transcriptional repression of the affected target gene. While PcG proteins are generally required to maintain the transcriptionally repressive state of homeotic genes throughout development, this protein is specifically required during the first 6 hours of embryogenesis to establish the repressed state. The Esc/E(z) complex is necessary but not sufficient for the repression of homeotic target genes, suggesting [...] (765 aa) | ||||
Aldh-III | Aldehyde dehydrogenase type III (Aldh-III) encodes a protein that confers a xenobiotic stress resistance by oxidising aromatic aldehydes (benzaldehyde). It also neutralises the lipid aldehydes formed after the attack of reactive oxygen and radicals, such as malondialdehyde during lipid peroxidation. The catalytic redox reaction uses NAD(P)+ as a cofactor. (564 aa) |
