A correction has been published by the journal *Nature* regarding research into how cells process ribosomal RNA (rRNA). The study, originally published online August 10, 2026, concerns the role of a protein called URB1 in ensuring proper rRNA processing.
The correction details that nucleolar URB1 ensures the removal of 3′ ETS rRNA to prevent exosome surveillance. This process is crucial for maintaining cellular health and preventing errors in protein synthesis.
The research, identified by DOI: 10.1038/s41586-026-10978-7, highlights the importance of URB1 in quality control within the nucleolus – a structure within cells responsible for ribosome production. By removing the 3′ ETS rRNA, URB1 prevents the exosome (a cellular surveillance complex) from identifying and degrading improperly processed RNA molecules.
The *Nature* correction serves to clarify details of the original publication and ensure accuracy in the scientific record regarding this specific mechanism of rRNA processing and quality control.
