molecular function |
| GO:0070180 | | large ribosomal subunit rRNA binding | | Interacting selectively and non-covalently with the large ribosomal subunit RNA (LSU rRNA), a constituent of the large ribosomal subunit. In S. cerevisiae, this is the 25S rRNA. |
| GO:0005515 | | protein binding | | Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules). |
| GO:0030295 | | protein kinase activator activity | | Binds to and increases the activity of a protein kinase, an enzyme which phosphorylates a protein. |
| GO:0003735 | | structural constituent of ribosome | | The action of a molecule that contributes to the structural integrity of the ribosome. |
biological process |
| GO:0032147 | | activation of protein kinase activity | | Any process that initiates the activity of an inactive protein kinase. |
| GO:0002181 | | cytoplasmic translation | | 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. |
| GO:0045860 | | positive regulation of protein kinase activity | | Any process that activates or increases the frequency, rate or extent of protein kinase activity. |
| GO:0006414 | | translational elongation | | The successive addition of amino acid residues to a nascent polypeptide chain during protein biosynthesis. |
cellular component |
| GO:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| GO:0022625 | | cytosolic large ribosomal subunit | | The large subunit of a ribosome located in the cytosol. |
| GO:0005622 | | intracellular | | The living contents of a cell; the matter contained within (but not including) the plasma membrane, usually taken to exclude large vacuoles and masses of secretory or ingested material. In eukaryotes it includes the nucleus and cytoplasm. |
| GO:0030529 | | intracellular ribonucleoprotein complex | | An intracellular macromolecular complex containing both protein and RNA molecules. |
| 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. |
| GO:0005840 | | ribosome | | 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: S). Hence, the prokaryotic ribosome (70S) comprises a large (50S) subunit and a small (30S) subunit, while the eukaryotic ribosome (80S) comprises a large (60S) subunit and a small (40S) subunit. Two sites on the ribosomal large subunit are involved in translation, namely the aminoacyl site (A site) and peptidyl site (P site). Ribosomes from prokaryotes, eukaryotes, mitochondria, and chloroplasts have characteristically distinct ribosomal proteins. |
