Protein

• UniProt ID: Q9BWK5
• Protein name: Cell cycle regulator of non-homologous end joining (Cell cycle regulator of NHEJ) (Modulator of retrovirus infection homolog)
• Protein function: Cell-cycle-specific regulator of classical non-homologous end joining (NHEJ) of DNA double-strand break (DSB) repair, which can act both as an activator or inhibitor of NHEJ, depending on the cell cycle phase (PubMed:24610814, PubMed:28959974).
