Complex: ERF1-ERF3 translation release factor complex
Macromolecular complex annotations are imported from the Complex Portal. These annotations have been derived from physical molecular interaction evidence extracted from the literature and cross-referenced in the entry, or by curator inference from information on homologs in closely related species or by inference from scientific background.

- Description
- Required for the termination of protein synthesis which occurs when one of three stop codons (UAA, UAG or UGA) enters the ribosomal A site. eRF1 stimulates GTP binding to eRF3, inducing the GTPase activity of eRF3 that couples codon recognition and eRF1 peptidyl-tRNA hydrolysis to ensure rapid and efficient peptide release from the ribosome.
Complex Diagram
This diagram displays the protein subunits (blue) of the complex and how they interact with each other. Interactions with other relevant participants such as small molecules (purple), sub-complexes (yellow), and other subunits (red) are also shown. If a participant appears in the diagram with no lines connected to it, then its specific interactions with other participants are currently unknown.

Shared Annotations
This diagram displays Gene Ontology terms (green) and subunits (blue) that are shared between the given macromolecular complex (black) and other yeast complexes (yellow). The shared GO terms or subunits can be visualized separately using the radio button at the bottom of the graph. Note: No diagram is shown ("No shared annotations") if there are less than 2 shared annotations (either GO terms or subunits of other complexes) between this complex and any other complexes.
