HHsearch alignment for GI: 254780872 and conserved domain: TIGR00446
>TIGR00446 nop2p NOL1/NOP2/sun family putative RNA methylase; InterPro: IPR011023 This domain is found in archaeal, bacterial and eukaryotic proteins. In the archaea and bacteria, they are primarily restricted to the euryarchaeota and proteobacteria respectively; where they are either described as either nucleolar protein or tRNA/rRNA cytosine-C5-methylase. They all have the S-adenosyl methionine (SAM) binding domain and are related to bacterial Fmu (16S rRNA m5C 967 methyltransferase) where the structure of the methyl transferase domain has been determined . In the eukaryota, the majority are annotated as being 'nucleolar protein'. None of the eukaryotic members in this family have a the SAM binding signature. Despite this, the yeast Nop2p is a probable RNA m(5)C methyltransferase, essential for processing and maturation of 27S pre-rRNA and large ribosomal subunit biogenesis ; localised to the nucleolus and is essential for viability . Reduced Nop2p expression limits yeast growth and decreases levels of mature 60S ribosomal subunits while altering rRNA processing . There is substantial identity between Nop2p and human p120 (NOL1), which is also called the proliferation-associated nucleolar antigen , . .
