DNA-binding protein involved in homologous recombination that acts by recruiting the MCM8-MCM9 helicase complex to sites of DNA damage to promote DNA repair synthesis (PubMed:31467087). A C-terminal region including the OB-fold stimulates the helicase activity of MCM8- MCM9 probably by altering its conformation (PubMed:37535404). . This is the function of Ensembl gene identifier ENSG00000125319 (HROB, homologous recombination factor with OB-fold).
