5-Metilcitozin je metilisana forma DNK baze citozina. On može da učestvuje u regulaciji transkripcija gena. Kad je citozin metilisan, DNA zadržava istu sekvencu, dok ekspresija metilisanih gena može da bude promenjena.[4][5][6] Epigenetika se bavi studiranjem ovih promena.[7][8]
In vivo
[уреди | уреди извор]5-Metilcitozin je epigenetička modifikacija formirana dejstvom DNK metiltransferaze.
