molecular function |
| GO:0043023 | | ribosomal large subunit binding | | Interacting selectively and non-covalently with any part of the larger ribosomal subunit. |
| GO:0043022 | | ribosome binding | | Interacting selectively and non-covalently with any part of a ribosome. |
| GO:0003743 | | translation initiation factor activity | | Functions in the initiation of ribosome-mediated translation of mRNA into a polypeptide. |
biological process |
| GO:1902626 | | assembly of large subunit precursor of preribosome | | The aggregation, arrangement and bonding together of a set of components to form the large subunit precursor of the preribosome. |
| GO:0000460 | | maturation of 5.8S rRNA | | Any process involved in the maturation of a precursor 5.8S ribosomal RNA (rRNA) molecule into a mature 5.8S rRNA molecule. |
| GO:0000470 | | maturation of LSU-rRNA | | Any process involved in the maturation of a precursor Large SubUnit (LSU) ribosomal RNA (rRNA) molecule into a mature LSU-rRNA molecule. |
| GO:0042256 | | mature ribosome assembly | | The aggregation, arrangement and bonding together of the large and small ribosomal subunits into a functional ribosome. |
| GO:0000054 | | ribosomal subunit export from nucleus | | The directed movement of a ribosomal subunit from the nucleus into the cytoplasm. |
| GO:0006412 | | translation | | 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. |
| GO:0006413 | | translational initiation | | The process preceding formation of the peptide bond between the first two amino acids of a protein. This includes the formation of a complex of the ribosome, mRNA or circRNA, and an initiation complex that contains the first aminoacyl-tRNA. |
cellular component |
| GO:0005829 | | cytosol | | The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes. |
| GO:0005730 | | nucleolus | | 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. |
| GO:0030687 | | preribosome, large subunit precursor | | 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. |
