| GO term | GO name | GO namespace | GO def |
| GO:0003677 | DNA binding | molecular_function | Any molecular function by which a gene product interacts selectively and non-covalently with DNA (deoxyribonucleic acid). [GOC:dph, GOC:jl, GOC:tb, GOC:vw] |
| GO:0003723 | RNA binding | molecular_function | Binding to an RNA molecule or a portion thereof. [GOC:jl, GOC:mah] |
| GO:0003735 | structural constituent of ribosome | molecular_function | The action of a molecule that contributes to the structural integrity of the ribosome. [GOC:mah] |
| GO:0005515 | protein binding | molecular_function | Binding to a protein. [GOC:go_curators] |
| GO:0008270 | zinc ion binding | molecular_function | Binding to a zinc ion (Zn). [GOC:ai] |
| GO:0002181 | cytoplasmic translation | biological_process | The chemical reactions and pathways resulting in the formation of a protein in the cytoplasm. This is a ribosome-mediated process in which the information in messenger RNA (mRNA) is used to specify the sequence of amino acids in the protein. [GOC:hjd] |
| GO:0006364 | rRNA processing | biological_process | Any process involved in the conversion of a primary ribosomal RNA (rRNA) transcript into one or more mature rRNA molecules. [GOC:curators] |
| GO:0006412 | translation | biological_process | The cellular metabolic process in which a protein is formed, using the sequence of a mature mRNA or circRNA molecule to specify the sequence of amino acids in a polypeptide chain. Translation is mediated by the ribosome, and begins with the formation of a ternary complex between aminoacylated initiator methionine tRNA, GTP, and initiation factor 2, which subsequently associates with the small subunit of the ribosome and an mRNA or circRNA. Translation ends with the release of a polypeptide chain from the ribosome. [GOC:go_curators] |
| GO:0042274 | ribosomal small subunit biogenesis | biological_process | A cellular process that results in the biosynthesis of constituent macromolecules, assembly, and arrangement of constituent parts of a small ribosomal subunit; includes transport to the sites of protein synthesis. [GOC:jl] |
| GO:0014069 | postsynaptic density | cellular_component | An electron dense network of proteins within and adjacent to the postsynaptic membrane of an asymmetric, neuron-neuron synapse. Its major components include neurotransmitter receptors and the proteins that spatially and functionally organize them such as anchoring and scaffolding molecules, signaling enzymes and cytoskeletal components. [GOC:BHF, GOC:dos, GOC:ef, GOC:jid, GOC:pr, GOC:sjp, http://molneuro.kaist.ac.kr/psd, PMID:14532281, Wikipedia:Postsynaptic_density] |
| GO:0005634 | nucleus | cellular_component | A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent. [GOC:go_curators] |
| GO:0005654 | nucleoplasm | cellular_component | That part of the nuclear content other than the chromosomes or the nucleolus. [GOC:ma, ISBN:0124325653] |
| 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:0005829 | cytosol | cellular_component | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. [GOC:hjd, GOC:jl] |
| GO:0005840 | ribosome | cellular_component | An intracellular organelle, about 200 A in diameter, consisting of RNA and protein. It is the site of protein biosynthesis resulting from translation of messenger RNA (mRNA). It consists of two subunits, one large and one small, each containing only protein and RNA. Both the ribosome and its subunits are characterized by their sedimentation coefficients, expressed in Svedberg units (symbol |
| GO:0022626 | cytosolic ribosome | cellular_component | A ribosome located in the cytosol. [GOC:mtg_sensu] |
| GO:0022627 | cytosolic small ribosomal subunit | cellular_component | The small subunit of a ribosome located in the cytosol. [GOC:mtg_sensu] |
| 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:0000028 | ribosomal small subunit assembly | biological_process | The aggregation, arrangement and bonding together of constituent RNAs and proteins to form the small ribosomal subunit. [GOC:jl, PMID:30467428] |
