PR-SET domain found in PR domain zinc finger protein 2 (PRDM2) and similar proteins
PRDM2 (also termed GATA-3-binding protein G3B, lysine N-methyltransferase 8, MTB-or MTE-binding protein, PR domain-containing protein 2, retinoblastoma protein-interacting zinc finger protein, or zinc finger protein RIZ) is S-adenosyl-L-methionine-dependent histone methyltransferase that specifically methylates 'Lys-9' of histone H3. It may function as a DNA-binding transcription factor.
