18S rRNA (guanine(1575)-N(7))-methyltransferase Bud23, C-terminal (IPR022238)

Short name: Bud23_C

Overlapping homologous superfamilies


Domain relationships



This entry represents the C-terminal domain of 18S rRNA (guanine(1575)-N(7))-methyltransferase Bud23 [PMID: 18332120]. Bud23 homologues can be found from yeast to human. They are S-adenosyl-L-methionine-dependent methyltransferases that specifically methylates the N7 position of a guanine in 18S rRNA [PMID: 25851604]. Bud23 homologue in Arabidopsis, known as Rid2 (ROOT INITIATION DEFECTIVE 2), is also involved in pre-rRNA processing [PMID: 21401745].

In humans, Bud23 is located in the Williams-Beuren syndrome (WBS) critical region [PMID: 11978965].
