| Primary Identifier | IPR012920 | Type | Domain |
| Short Name | rRNA_MeTfrase_SPB1-like_C |
| description | This domain is found at the C terminus SPB1-like proteins. This domain interacts with the meandering tail of Erb1 and its removal is required to form the pre-mature inter-subunit surface of the Arx1/Nog2 particle [, ].SPB1 is an adoMet-dependent rRNA methyltransferase required for proper assembly of pre-ribosomal particles during the biogenesis of the 60S ribosomal subunit []. In Saccharomyces cerevisiae, it specifically methylates the guanosine in position 2922 of the 25S rRNA at thestage of 27S pre-rRNA maturation []. It interacts with the snoRNA-associated proteins Nop1 and Nop58 []. FTSJ3, SPB1 homologue in humans, is associated with NIP7 (involved in the biogenesis of 40S subunit) and functions in pre-rRNA processing []. |
