General annotation (Comments)

Function	Directs the termination of nascent peptide synthesis (translation) in response to the termination codons UAA, UAG and UGA. Component of the transient SURF complex which recruits UPF1 to stalled ribosomes in the context of nonsense-mediated decay (NMD) of mRNAs containing premature stop codons. Ref.2
Subunit structure	Heterodimer of two subunits, one of which binds GTP. Component of the transient SURF (SMG1-UPF1-eRF1-eRF3) complex. Ref.9
Subcellular location	Cytoplasm.
Sequence similarities	Belongs to the eukaryotic release factor 1 family.
