The testis-enriched histone demethylase, KDM4D, regulates methylation of histone H3 lysine 9 during spermatogenesis in the mouse but is dispensable for fertility.

ABSTRACT: Epigenetic modifications, and methylation of histones in particular, dynamically change during spermatogenesis. Among various methylations of histone H3, methylation of histone H3 lysine 9 (H3K9) and its regulation are essential for spermatogenesis. Trimethytransferases as well as dimethyltransferase are required for meiotic progression. In addition, didemethylase of H3K9 is also critical for spermatogenesis through transcriptional regulation of spermatid-specific genes. However, the requirement for demethylation of trimethylated H3K9 (H3K9me3) during spermatogenesis remains to be elucidated. Here, we report the targeted disruption of KDM4D, a testis-enriched tridemethylase of H3K9. Kdm4d-null mice are viable and fertile and do not show any obvious phenotype. However, H3K9me3 accumulates s
