PR domain zinc finger protein 9 is a protein that in humans is encoded by the Prdm9 gene. The protein has histone H3K4 trimethyltransferase activity, a KRAB domain, and a DNA-binding domain consisting of multiple tandem C2H2 zinc finger (ZF) domains. PRDM9 specifically trimethylates lysine 4 of histone H3 during meiotic prophase and is essential for proper meiotic progression, but does not have the ability to mono- and dimethylate lysine 4 of histone H3. H3K4 methylation represents a specific tag for epigenetic transcriptional activation which plays a central role in the transcriptional activation of genes during early meiotic prophase.
