E3 ubiquitin-protein ligase CCNB1IP1 is an enzyme that in humans is encoded by the CCNB1IP1 gene.56

HEI10 is a member of the E3 ubiquitin ligase family and functions in progression of the cell cycle through G(2)/M.[supplied by OMIM]6 It is considered a housekeeping gene.

During meiosis, crossing over between homologous chromosomes (homologs) facilitates accurate chromosome segregation.7 In mammals, the ring-domain protein CCNB1IP1, also known as HEI10, promotes crossing over between each pair of homologs during meiosis.7 Studies in the mouse showed that this pro-crossover ring-domain protein facilitates the homologous recombination and DNA repair processes that produce crossovers.7
