NMR Structure(hide GO term definitions)
Chain A   (SUI1_YEAST | P32911)
molecular function
    GO:0043024    ribosomal small subunit binding    Interacting selectively and non-covalently with any part of the small ribosomal subunit.
    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:0001731    formation of translation preinitiation complex    The joining of the small ribosomal subunit, ternary complex, and mRNA.
    GO:1990145    maintenance of translational fidelity    Suppression of the occurrence of translational errors, such as codon-anticodon mis-paring, during the process of translation of a protein using an mRNA template.
    GO:0006417    regulation of translation    Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA.
    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:0016282    eukaryotic 43S preinitiation complex    A protein complex composed of the 40S ribosomal subunit plus eIF1A, eIF3, and eIF2-GTP-bound methionyl-initiator methionine tRNA.
    GO:0043614    multi-eIF complex    A multifactor complex composed of multiple translation initiation factors and the initiatior tRNAiMet, which is ready to bind to the small (40S) ribosome to form the 43S preinitiation complex. In S. cerevisiae, this complex is composed of eIF1, eIF2, eIF3, and eIF5.
