FunFam 204: Translation elongation factor Tu

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

GO Term Annotations Evidence
Translation GO:0006412
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.
3 Q385F3 (/ISA) Q385F3 (/ISA) Q7YZN6 (/ISA)
Posttranscriptional regulation of gene expression GO:0010608
Any process that modulates the frequency, rate or extent of gene expression after the production of an RNA transcript.
3 Q385F3 (/IDA) Q385F3 (/IDA) Q7YZN6 (/IDA)

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.
2 Q9Y450 (/TAS) Q9Y450 (/TAS)
Signal transduction GO:0007165
The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.
2 Q9Y450 (/TAS) Q9Y450 (/TAS)
Ribosome disassembly GO:0032790

2 Q9Y450 (/TAS) Q9Y450 (/TAS)
Positive regulation of translation GO:0045727
Any process that activates or increases the frequency, rate or extent of the chemical reactions and pathways resulting in the formation of proteins by the translation of mRNA or circRNA.
2 P32769 (/IMP) P32769 (/IMP)
Nonfunctional rRNA decay GO:0070651
An rRNA catabolic process that results in the targeted detection and degradation of aberrant rRNAs contained within translationally defective ribosomes, thereby acting as a quality-control system.

Nuclear-transcribed mRNA catabolic process, no-go decay GO:0070966
