Cell cycle regulator of non-homologous end joining is a protein that in humans is encoded by the CYREN gene.

It prevents classical non-homologous end joining, a method of repair of double-stranded DNA breaks.[1] This protein is therefore important in regulating DNA repair.

When alternatively spliced, is predicted to produce three different micropeptides.[2]

  • MRI-1 was previously found to be a modulator of retrovirus infection.[2]
  • MRI-2 may be important in non-homologous end joining (NHEJ) of DNA double strand breaks. In Co-Immunoprecipitation experiments, MRI-2 bound to Ku70 and Ku80, two subunits of Ku, which play a major role in the NHEJ pathway.[2]
  • MRI-3
