CXXC finger protein 1 (CFP1, Cfp1, CXXC1, Cxxc1) is a critical component of the SET domain-containing 1A histone lysine methyltransferase complex that catalyzes histone H3K4 methylation and has a specific binding domain for unmethylated CpG DNA. However, our current understanding of CFP1's role in the genome-wide regulation of DNA and H3K4 methylation remains limited.</p><p><strong>Methods: </strong>We performed genome-wide methylation analysis using reduced-representation bisulfite sequencing on spermatocytes isolated from Cfp1 knockout and wild-type mice.
