Affinity Capture-RNA
An interaction is inferred when a bait protein is affinity captured from cell extracts by either polyclonal antibody or epitope tag and associated RNA species identified by Northern blot, RT-PCR, affinity labeling, sequencing, or microarray analysis.
Publication
The nucleolar protein Nop19p interacts preferentially with Utp25p and Dhr2p and is essential for the production of the 40S ribosomal subunit in Saccharomyces cerevisiae.
In eukaryotes, ribosome biogenesis is a process of major interest that requires more than 200 factors acting coordinately in time and space. Using genetic and proteomic studies, most of the components have now been identified. Based on its nucleolar localization, we characterized the protein encoded by the open reading frame YGR251W, we renamed Nop19p as playing an essential role in ... [more]
