FunFam 388: U6 small nuclear RNA (adenine-(43)-N(6))-methyltra...

There are 1 EC terms in this cluster

Please note: EC annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

Note: The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.

EC Term Annotations Evidence
U6 snRNA m(6)A methyltransferase. [EC: 2.1.1.346]
S-adenosyl-L-methionine + adenine in U6 snRNA = S-adenosyl-L-homocysteine + N(6)-methyladenine in U6 snRNA.
  • This enzyme, found in vertebrates, methylates a specific adenine in a hairpin structure of snRNA.
  • The effects of the binding of the methyltransferase to its substrate is important for the regulation of the activity of an isoform of EC 2.5.1.6, that produces S-adenosyl-L-methionine.
  • The enzyme also binds (and maybe methylates) the lncRNAs XIST and MALAT1 as well as a number of pre-mRNAs at specific positions often found in the intronic regions.
