General Information

Term

cleavage in ITS2 between 5.8S rRNA and LSU-rRNA of tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA)

ID (Ontology)

GO:0000448 (Gene Ontology)

Definition

Endonucleolytic cleavage within ITS2 between the 5.8S rRNA and the LSU-rRNA of an rRNA molecule originally produced as a tricistronic rRNA transcript that contained the Small SubUnit (SSU) rRNA, the 5.8S rRNA, and the Large SubUnit (LSU) rRNA, in that order, from 5' to 3' along the primary transcript.[ PubMed:10690410 ]

Also Known As

"cleavage in ITS2 of tricistronic rRNA transcript to separate 5.8S and LSU rRNAs (SSU-rRNA, 5.8S rRNA, LSU-rRNA)"
