CC -!- FUNCTION: S-adenosyl-L-methionine-dependent methyltransferase that has
CC the ability to methylate both RNAs and proteins. Involved in pre-rRNA
CC processing. Utilizes the methyl donor S-adenosyl-L-methionine to
CC catalyze the site-specific 2'-hydroxyl methylation of ribose moieties
CC in pre-ribosomal RNA. Site specificity is provided by a guide RNA that
CC base pairs with the substrate. Methylation occurs at a characteristic
CC distance from the sequence involved in base pairing with the guide RNA.
CC Also acts as a protein methyltransferase by mediating methylation of
CC 'Gln-105' of histone H2A (H2AQ105me), a modification that impairs
CC binding of the FACT complex and is specifically present at 35S
CC ribosomal DNA locus (By similarity). {ECO:0000250}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=L-glutaminyl-[histone H2A] + S-adenosyl-L-methionine = H(+) +
CC N(5)-methyl-L-glutaminyl-[histone H2A] + S-adenosyl-L-homocysteine;
CC Xref=Rhea:RHEA:50904, Rhea:RHEA-COMP:12837, Rhea:RHEA-COMP:12839,
CC ChEBI:CHEBI:15378, ChEBI:CHEBI:30011, ChEBI:CHEBI:57856,
CC ChEBI:CHEBI:59789, ChEBI:CHEBI:61891;
CC -!- SUBUNIT: Component of box C/D small nucleolar ribonucleoprotein
CC (snoRNP) particles that contain SNU13, NOP1, SIK1/NOP56 and NOP58, plus
CC a guide RNA. {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Nucleus, nucleolus {ECO:0000250}. Note=Fibrillar
CC region of the nucleolus. {ECO:0000250}.
CC -!- PTM: By homology to other fibrillarins, some or all of the N-terminal
CC domain arginines are modified to asymmetric dimethylarginine (DMA).
CC {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the methyltransferase superfamily. Fibrillarin
CC family. {ECO:0000305}.
