| GO:0003723 | RNA binding | molecular_function | Binding to an RNA molecule or a portion thereof. [GOC:jl, GOC:mah] |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
| GO:0042134 | rRNA primary transcript binding | molecular_function | Binding to an unprocessed ribosomal RNA transcript. [GOC:jl] |
| GO:0005730 | nucleolus | cellular_component | A small, dense body one or more of which are present in the nucleus of eukaryotic cells. It is rich in RNA and protein, is not bounded by a limiting membrane, and is not seen during mitosis. Its prime function is the transcription of the nucleolar DNA into 45S ribosomal-precursor RNA, the processing of this RNA into 5.8S, 18S, and 28S components of ribosomal RNA, and the association of these components with 5S RNA and proteins synthesized outside the nucleolus. This association results in the formation of ribonucleoprotein precursors; these pass into the cytoplasm and mature into the 40S and 60S subunits of the ribosome. [ISBN:0198506732] |
| GO:0000470 | maturation of LSU-rRNA | biological_process | Any process involved in the maturation of a precursor Large SubUnit (LSU) ribosomal RNA (rRNA) molecule into a mature LSU-rRNA molecule. [GOC:curators] |
| GO:0000460 | maturation of 5.8S rRNA | biological_process | Any process involved in the maturation of a precursor 5.8S ribosomal RNA (rRNA) molecule into a mature 5.8S rRNA molecule. [GOC:curators] |
| GO:0030687 | preribosome, large subunit precursor | cellular_component | A preribosomal complex consisting of 27SA, 27SB, and/or 7S pre-rRNA, 5S rRNA, ribosomal proteins including late-associating large subunit proteins, and associated proteins; a precursor of the eukaryotic cytoplasmic large ribosomal subunit.
