function
FUNCTION: S-adenosyl-L-methionine-dependent methyltransferase that specifically methylates the C(5) position of cytosine 4447 in 28S rRNA. Required for efficient rRNA processing and 60S ribosomal subunit biogenesis. Regulates pre-rRNA processing through non-catalytic complex formation with box C/D snoRNAs and facilitates the recruitment of U3 and U8 snoRNAs to pre-90S ribosomal particles and their stable assembly into snoRNP complexes. May play a role in the regulation of the cell cycle and the increased nucleolar activity that is associated with the cell proliferation. {ECO:0000250|UniProtKB:P46087}.
