Kdm4A | Lysine (K)-specific demethylase 4A (Kdm4A) encodes a histone lysine demethylase that catalyzes removal of methyl groups using alpha-ketoglutarate as a cofactor. It demethylates H3K36me3 and is implicated in the demethylation of H3K9me3 and H3K56me3. Its roles include transcription, DNA repair, and heterochromatin silencing. (495 aa) | ||||
Ogg1 | DNA-(apurinic or apyrimidinic site) lyase; DNA repair enzyme that incises DNA at 8-oxoG residues. Excises 7,8-dihydro-8-oxoguanine and 2,6-diamino-4-hydroxy-5-N- methylformamidopyrimidine (FAPY) from damaged DNA. Has a beta-lyase activity that nicks DNA 3' to the lesion. Efficiently incises DNA duplexes containing 8-hydroxyguanine (8-OH-Gua), 8-hydroxyadenine (8- OH-Ade) and abasic (AP) sites placed opposite to a cytosine. (343 aa) |
