Full name: dimethyladenosine transferase
Synonym: DIMT1
GI: 1143076922
Structures: | |
Enzyme type: methyltransferase
Position of modification - modification: s:1850(1518) - m6,6A
s:1851(1519) - m6,6A


DIMT1L is responsible for N6,N6 dimethylation at positions A1850 and A1851. Enzyme is required for distinct pre-rRNA processing reactions leading to synthesis of 18S rRNA, and it has been demonstrated that in human cells, as in budding yeast, ribosome biogenesis requires the presence of the modification enzyme rather than its RNA-modifying catalytic activity.
