General Information

Term

nucleolar ribonuclease P complex

ID (Ontology)

GO:0005655 (Gene Ontology)

Definition

A ribonuclease P complex located in the nucleolus of a eukaryotic cell, where it catalyzes the 5' endonucleolytic cleavage of precursor tRNAs to yield mature tRNAs. Eukaryotic nucleolar ribonuclease P complexes generally contain a single RNA molecule that is necessary but not sufficient for catalysis, and several protein molecules.[ PubMed:12045094 ]

Also Known As
