Abstract

Lysine crotonylation (Kcr) is a newly identified histone modification that is associated with active transcription in mammalian cells. Here we report that the chromodomain Y-like transcription corepressor CDYL negatively regulates histone Kcr by acting as a crotonyl-CoA hydratase to convert crotonyl-CoA to β-hydroxybutyryl-CoA. We showed that the negative regulation of histone Kcr by CDYL is intrinsically linked to its transcription repression activity and functionally implemented in the reactivation of sex chromosome-linked genes in round spermatids and genome-wide histone replacement in elongating spermatids. Significantly, Cdyl transgenic mice manifest dysregulation of histone Kcr and reduction of male fertility with a decreased epididymal sperm count and sperm cell motility. Our study uncovers a biochemical pathway in the regulation of histone Kcr and implicates CDYL-regulated histone Kcr in spermatogenesis, adding to the understanding of the physiology of male reproduction and the mechanism of the spermatogenic failure in AZFc (Azoospermia Factor c)-deleted infertile men.
