Mitohondrijski faktor 1 translacijskog oslobađanja, znan i kao MTRF1 je ljudski gen na hromosomu 13, sekvenca 13q14.11, između bazmih prova 41,216.369 i 41,263.577.^[5]^[6]

Protein kodiran ovim genom usmjerava završetak translacije kao odgovor na peptidnu sekvencu terminacijskih kodonia. U početku se smatralo da ima ulogu u prekidu sinteze mitohondrijskih proteina. Pretpostavljeno je da mtRF1 kod kičmenjaka prepoznaje nestandardne stop kodone AGA i AGG. Alternativno, na temelju detaljnog 3D modeliranja, predloženo je da se prepoznaju zaostali ribosomi, u kojima je tRNK još uvijek vezana za peptidni lanac, ali u kojima je ribosomsko A-mjesto prazno.

Aminokiselinska sekvenca uredi

Dužina polipeptidnog lanca je 445 aminokiselina, a molekulska težina 52 306 Da.^[7]
