Comments [?]

case <OC:Fungi>
Function Required for proper assembly of pre-ribosomal particles during the biogenesis of the 60S ribosomal subunit.
Catalytic activity RHEA:48628: a ribonucleotide in rRNA + S-adenosyl-L-methionine = a 2'-O-methylribonucleotide in rRNA + H(+) + S-adenosyl-L-homocysteine
Subunit Component of the nucleolar and nucleoplasmic pre-60S ribosomal particle.
else case <OC:Vertebrata>
Function Probable methyltransferase involved in the processing of the 34S pre-rRNA to 18S rRNA and in 40S ribosomal subunit formation.
Catalytic activity RHEA:48628: a ribonucleotide in rRNA + S-adenosyl-L-methionine = a 2'-O-methylribonucleotide in rRNA + H(+) + S-adenosyl-L-homocysteine
Subunit Interacts with NIP7.
else
Function Probable methyltransferase involved in the maturation of rRNA and in the biogenesis of ribosomal subunits.
Catalytic activity RHEA:48628: a ribonucleotide in rRNA + S-adenosyl-L-methionine = a 2'-O-methylribonucleotide in rRNA + H(+) + S-adenosyl-L-homocysteine
end case
Subcellular location Nucleus, nucleolus.
Similarity Belongs to the class I-like SAM-binding methyltransferase superfamily. RNA methyltransferase RlmE family. SPB1 subfamily.
