FunFam 4: Protein DOM34 homolog

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.

Dom34-Hbs1 complex GO:1990533
A protein complex consisting of one subunit known as Dom34 or Pelota that has similarity to translation termination factor eRF1, and another subunit, Hbs1, that is a GTPase with similarity to translation termination factor eRF3. The Dom34-Hbs1 complex has a role in cotranslational mRNA quality control by promoting ribosomal subunit dissociation and peptidyl-tRNA release when translation is stalled, facilitating no-go decay and nonstop decay.

Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
