20S-pre-rRNA D-site endonuclease NOB1

UniProtKB accession:  Q08444

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Required for the synthesis of 40S ribosome subunits. Has a role in processing 20S pre-rRNA into the mature 18S rRNA, where it is required for cleavage at the 3' end of the mature 18S rRNA (D-site). Accompanies the 20S pre-rRNA from the nucleus to the cytoplasm. In association with NIN1, may promote the recruitment of the proteasome to the ribosomal subunits stalled in maturation.
