Human SETD8/PR-Set7 recombinant protein
Protein-lysine N-methyltransferase that monomethylates both histones and non-histone proteins. Specifically monomethylates 'Lys-20' of histone H4 (H4K20me1). H4K20me1 is enriched during mitosis and represents a specific tag for epigenetic transcriptional repression. Mainly functions in euchromatin regions, thereby playing a central role in the silencing of euchromatic genes. Required for cell proliferation, probably by contributing to the maintenance of proper higher-order structure of DNA during mitosis. Involved in chromosome condensation and proper cytokinesis. Nucleosomes are preferred as substrate compared to free histones. Mediates monomethylation of p53/TP53 at 'Lys-382', leading to repress p53/TP53-target genes. Plays a negative role in TGF-beta response regulation and a positive role in cell migration.

A DNA sequence encoding the human SETD8 (NP_065115.3) (Lys 195-His 352) was expressed and purified, with two additional amino acids (Gly & Pro) at the N-terminus.
The recombinant human SETD8 comprises 160 amino acids and has a predicted molecular mass of 18.2 kDa. It migrates as an approximately 18 kDa band in SDS-PAGE under reducing conditions as predicted.
