| molecular function |
|---|
| | GO:0005525 | | GTP binding | | Interacting selectively and non-covalently with GTP, guanosine triphosphate. |
| | GO:0003924 | | GTPase activity | | Catalysis of the reaction: GTP + H2O = GDP + phosphate. |
| | GO:0016787 | | hydrolase activity | | Catalysis of the hydrolysis of various bonds, e.g. C-O, C-N, C-C, phosphoric anhydride bonds, etc. Hydrolase is the systematic name for any enzyme of EC class 3. |
| | GO:0046872 | | metal ion binding | | Interacting selectively and non-covalently with any metal ion. |
| | GO:0000166 | | nucleotide binding | | Interacting selectively and non-covalently with a nucleotide, any compound consisting of a nucleoside that is esterified with (ortho)phosphate or an oligophosphate at any hydroxyl group on the ribose or deoxyribose. |
| | 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. |
| | GO:0031369 | | translation initiation factor binding | | Interacting selectively and non-covalently with a translation initiation factor, any polypeptide factor involved in the initiation of ribosome-mediated translation. |
| biological process |
|---|
| | GO:0001732 | | formation of cytoplasmic translation initiation complex | | Joining of the large subunit, with release of IF2/eIF2 and IF3/eIF3. This leaves the functional ribosome at the AUG, with the methionyl/formyl-methionyl-tRNA positioned at the P site. |
| | GO:0000462 | | maturation of SSU-rRNA from tricistronic rRNA transcript (SSU-rRNA, 5.8S rRNA, LSU-rRNA) | | Any process involved in the maturation of a precursor Small SubUnit (SSU) ribosomal RNA (rRNA) molecule into a mature SSU-rRNA molecule from the pre-rRNA molecule originally produced as a tricistronic rRNA transcript that contains the Small Subunit (SSU) rRNA, 5.8S rRNA, and the Large Subunit (LSU) in that order from 5' to 3' along the primary transcript. |
| | GO:0006446 | | regulation of translational initiation | | Any process that modulates the frequency, rate or extent of translational initiation. |
| | GO:0042255 | | ribosome assembly | | The aggregation, arrangement and bonding together of the mature ribosome and of its subunits. |
| | 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:0005737 | | cytoplasm | | All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures. |
| | GO:0022627 | | cytosolic small ribosomal subunit | | The small subunit of a ribosome located in the cytosol. |
| | GO:0033290 | | eukaryotic 48S preinitiation complex | | A protein complex composed of the small ribosomal subunit, eIF3, eIF1A, methionyl-initiatior methionine and a capped mRNA. The complex is initially positioned at the 5'-end of the capped mRNA. |
