DNK (citozin-5)-metiltransferaza 3 beta, je enzim koji je kod ljudi kodiran DNMT3B genom.^[4] Mutacije ovog gena su asocirane sa imunodeficijencijom, nestabilnosti centromera i sindromom anomalija lica.^[5]

Funkcija

CpG metilacija je epigenetska modifikacija koja je važna za embrionalni razvoj, utiskivanje i inaktivaciju X-hromozoma. Studije na miševima su pokazale da je metilacija DNK potrebna za razvoj sisara. Ovaj gen kodira DNK metiltransferazu za koju se smatra da funkcioniše u de novo metilaciji, a ne u održavanju metilacije. Protein se prvenstveno lokalizuje u jedru i njegova ekspresija je razvojno regulisana. Opisano je osam alternativno spojenih varijanti transkripta. Sekvence pune dužine varijanti 4 i 5 nisu određene.^[4]

Klinički značaj

Sindrom imunodeficijencije-centromerne nestabilnosti-anomalije lica (ICF) je rezultat defekata u sazrevanju limfocita koji su rezultat aberantne metilacije DNK uzrokovane mutacijama u genu DNMT3B.^[5]

Varijante ovog gena takođe mogu doprineti zavisnosti od nikotina.^[6]

Interakcije

Pokazano je da DNMT3B formira interakcije sa:
