PR domain zinc finger protein 9; histone-lysine N-methyltransferase PRDM9; PR domain-containing protein 9 (PRDM9, PFM6)

Function: - histone methyltransferase - specifically trimethylates Lys-4 of histone H3 during meiotic prophase & is essential for proper meiotic progression - does not have the ability to mono- & dimethylate Lys-4 of histone H3 - H3 Lys-4 methylation represents a specific tag for epigenetic transcriptional activation - role in transcriptional activation of genes during early meiotic prophase S-adenosyl-L-methionine + L-lysine-[histone] = S-adenosyl-L-homocysteine + N(6)-methyl-L-lysine-[histone] Structure: - contains 14 C2H2-type Zn+2 fingers - contains 1 KRAB-related domain - contains 1 SET domain Compartment: - nucleus (putative) - chromosome
