GO term | GO name | GO namespace | GO def |
GO:0003723 | RNA binding | molecular_function | Binding to an RNA molecule or a portion thereof. [GOC:jl, GOC:mah] |
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:0005654 | nucleoplasm | cellular_component | That part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653] |
GO:0032040 | small-subunit processome | cellular_component | A large ribonucleoprotein complex that is an early preribosomal complex. In S. cerevisiae, it has a size of 80S and consists of the 35S pre-rRNA, early-associating ribosomal proteins most of which are part of the small ribosomal subunit, the U3 snoRNA and associated proteins.

GO:0030515 | snoRNA binding | molecular_function | Binding to a small nucleolar RNA. [GOC:mah] |
GO:0031965 | nuclear membrane | cellular_component | Either of the lipid bilayers that surround the nucleus and form the nuclear envelope; excludes the intermembrane space. [GOC:mah, GOC:pz] |
GO:0032991 | protein-containing complex | cellular_component | A stable assembly of two or more macromolecules, i.e. proteins, nucleic acids, carbohydrates or lipids, in which at least one component is a protein and the constituent parts function together. [GOC:dos, GOC:mah] |
GO:0030490 | maturation of SSU-rRNA | biological_process | Any process involved in the maturation of a precursor Small SubUnit (SSU) ribosomal RNA (rRNA) molecule into a mature SSU-rRNA molecule. [GOC:curators] |
