Summary: Enables endoribonuclease activity and small ribosomal subunit rRNA binding activity. Involved in maturation of SSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA) and proteasome assembly. Located in nucleus. Part of preribosome, small subunit precursor. Used to study colorectal cancer. Orthologous to human NOB1 (NIN1 (RPN12) binding protein 1 homolog). [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?

Data report that cleavage of pre-rRNA at the 3'-end of 18 S rRNA, requires functional interactions between Nob1 and Prp43, and the cofactor Pfa1.
Title: RNA helicase Prp43 and its co-factor Pfa1 promote 20 to 18 S rRNA processing catalyzed by the endonuclease Nob1.
Data demonstrate that Nob1's binding site centers around the 3'-end of 18S rRNA and also locate Nob1's suggested active site.
Title: Nob1 binds the single-stranded cleavage site D at the 3'-end of 18S rRNA with its PIN domain.

Preferred Names: rRNA-binding endoribonuclease

NP_014699.1

Protein involved in proteasomal and 40S ribosomal subunit biogenesis; required for cleavage of the 20S pre-rRNA to generate the mature 18S rRNA; cleavage is activated by Fun12p, a GTPase and translation initiation factor; relocalizes from nucleus to nucleolus upon DNA replication stress
