Ribosome biogenesis protein NOP53

UniProtKB accession:  Q12080

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Late-acting factor in the nuclear maturation of 60S ribosomal subunits, which is required for normal acquisition of export competence. Required for the export of the large subunit. Acts to stimulate the RNase activity of the exosome complex, and may recruit the exosome to 7S pre-rRNA for processing. Associates with numerous RNAs including the 27S and 7S pre-rRNAs and the box H/ACA snoRNA snR37. Also interacts (via N-terminal region) with the mature 25S rRNA and the mature 5.8S rRNA.
