We obtained HP1 gamma mutant mice and found that all homozygous mice were infertile as a result of defects in meiosis. Some kinds of histone methylation at pericentromeric heterochromatin were reduced in the mutant spermatocytes and spermatogonia. Moreover, a methyltransferase of H3K9 in spermatocytes could not accumulate in the mutant spermatocytes. These findings suggest that HP1 gamma is essential for recruitment of histone modification factors at pericentromeric heterochromatin and histone modifications are required for progression of meiosis.
