CC   -!- FUNCTION: Involved in mitochondrial ribosome assembly. 5-methylcytosine
CC       rRNA methyltransferase that probably is involved in mitochondrial
CC       ribosome small subunit (SSU) maturation by methylation of mitochondrial
CC       12S rRNA; the function is independent of MTERFD2/MTERF4 and assembled
CC       mitochondrial ribosome large subunit (LSU). Targeted to LSU by
CC       MTERFD2/MTERF4 and probably is involved in a final step in ribosome
CC       biogenesis to ensure that SSU and LSU are assembled. In vitro can
CC       methylate 16S rRNA of the LSU; the methylation is enhanced by
CC       MTERFD/MTERF4. {ECO:0000269|PubMed:21531335,
