Chain P   (IF2M_BOVIN | P46198)
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: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:0043024    ribosomal small subunit binding    Interacting selectively and non-covalently with any part of the small ribosomal subunit.
    GO:0008135    translation factor activity, RNA binding    Functions during translation by interacting selectively and non-covalently with RNA during polypeptide synthesis at the ribosome.
    GO:0003743    translation initiation factor activity    Functions in the initiation of ribosome-mediated translation of mRNA into a polypeptide.
biological process
    GO:0070124    mitochondrial translational initiation    The process preceding formation of the peptide bond between the first two amino acids of a protein in a mitochondrion. This includes the formation of a complex of the ribosome, mRNA, and an initiation complex that contains the first aminoacyl-tRNA.
    GO:0032790    ribosome disassembly    The disaggregation of a ribosome into its constituent components; includes the dissociation of ribosomal 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: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:0005759    mitochondrial matrix    The gel-like material, with considerable fine structure, that lies in the matrix space, or lumen, of a mitochondrion. It contains the enzymes of the tricarboxylic acid cycle and, in some organisms, the enzymes concerned with fatty acid oxidation.
    GO:0005739    mitochondrion    A semiautonomous, self replicating organelle that occurs in varying numbers, shapes, and sizes in the cytoplasm of virtually all eukaryotic cells. It is notably the site of tissue respiration.
    GO:0005654    nucleoplasm    That part of the nuclear content other than the chromosomes or the nucleolus.
