    General gene information

    Go to the top of the page Help
    • C/D box small nucleolar RNA (snoRNA); acts as antisense guide to target RNA base acetylation by Kre33p to cytosine 1773 in 18S rRNA (responsible for ac4C 1773); establishes extended bipartite complementarity around the cytosines targeted for acetylation, similar to pseudouridylation pocket formation by the H/ACA snoRNPs; base pairing between snR45 and 18S rRNA requires the putative helicase activity of Kre33p
