PRDM9
PR domain[note 1] zinc finger protein 9 is a protein that in humans is encoded by the Prdm9 gene.[1] The protein has histone H3(K4) trimethyltransferase activity, a KRAB domain, and a DNA-binding domain consisting of multiple tandem C2H2 zinc finger (ZF) domains.[2] PRDM9 specifically trimethylates 'Lys-4' of histone H3 during meiotic prophase and is essential for proper meiotic progression, but does not have the ability to mono- and dimethylate 'Lys-4' of histone H3. H3 'Lys-4' methylation represents a specific tag for epigenetic transcriptional activation which plays a central role in the transcriptional activation of genes during early meiotic prophase.
Function
PRDM9 is thought to mediate the process of meiotic homologous recombination.[3]
