Both MTRF1L and ICT1 can bind a standard stop codon in the A-site of the ribosome and cause release of the polypeptide. ICT1 can also cause release of ribosomes stalled in non-standard conformations (e.g. non-standard stop codons, mRNA lacking a stop codon) (inferred from pig mitoribosomes in Akabane et al. 2014).
