Protein
27S pre-rRNA (guanosine(2922)-2'-O)-methyltransferase
Gene
SPB1, YCL054W, YCL431, YCL54W
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

Required for proper assembly of pre-ribosomal particles during the biogenesis of the 60S ribosomal subunit. Specifically methylates the guanosine in position 2922 of the 25S rRNA at the stage of 27S pre-rRNA maturation. Methylates also the uridine in position 2921 in the absence of methylation of this residue guided by snoRNA snR52 at the stage of 35S pre-rRNA maturation.3 Publications

Catalytic activityi

S-adenosyl-L-methionine + guanosine(2922) in 27S pre-rRNA = S-adenosyl-L-homocysteine + 2'-O-methylguanosine(2922) in 27S pre-rRNA.1 Publication
