Abstract: Managing meiosis Meiosis is a unique cell division that is necessary for sexual reproduction; it produces functional haploid gametes and shuffles genomic information. Progression through meiosis is controlled by the proper orchestration of a number of meiotic genes. A candidate gene for regulating meiotic gene expression has now been identified. Meisetz, encoding a meiosis-specific histone H3 lysine 4-specific trimethyltransferase, is essential for meiotic recombination between homologous chromosomes in mice. Meisetz has essential functions in spermatocytes through epigenetic modification of chromatin, the first instance of a gene regulating epigenetic control of gene expression during meiotic progression.
