PR domain containing 2; with ZNF domain (PRDM2); also known as zinc finger protein RIZ; is a member of histone methyltransferase (HMT) class enzymes that methylate lysine residues of histones or proteins. HMTs contain a conserved catalytic core termed the SET domain; which shares sequence homology with an independently described sequence motif; the PR domain. PRDM2 is a protein that has eight C2H2-type zinc fingers and a unique SET domain, as well as being highly expressed in retinoblastoma cell lines and brain tumors; it's also found in different cell lines and brains, heart, skeletal muscle, liver and spleen. PRDM2 is a S-adenosyl-L-methionine-dependent histone methyltransferase that specifically methylates 'Lys-9' of histone H3; and is identified as a tumor suppressor. It is thought that the PR( SET) sequence is essential for tumor suppression activities; in human malignancies, changes in the PR domain resulted in reduced activity. Additionally, S-adenosylhomocysteine or a methyl donor deficit impairs RIZ1 and other H3 lysine 9 methylation functions. PRDM2 may also function as a DNA-binding transcription factor. It binds to the macrophage-specific TPA-responsive element (MTE) in the HMOX1 (heme oxygenase 1) gene and acts as a transcriptional activator. PRDM2 (RIZ) binds to the retinoblastoma protein (RB) and interacts with GATA3, in addition. Human PRDM2/RIZ1 Recombinant Protein is a highly pure recombinant protein developed by Assay Genie for use in a range of applications.
