SETD8 / PR-Set7 recombinant protein
Recombinant Human SETD8 / PR-Set7 Protein
NCBI and Uniprot Product Information
NCBI Description
The protein encoded by this gene is a protein-lysine N-methyltransferase that can monomethylate Lys-20 of histone H4 to effect transcriptional repression of some genes. The encoded protein is required for cell proliferation and plays a role in chromatin condensation. [provided by RefSeq, May 2016]
Uniprot Description
SETD8: a protein-lysine N-methyltransferase that monomethylates both histones and non-histone proteins. Methylates K20 of histone H4 (H4K20me1), a specific tag for epigenetic transcriptional repression. SETD8 protein and H4K20me1 levels are cell cycle regulated, both increasing in S phase and peaking at G2/M phase. Interacts with the PCNA protein, associates with sites of active DNA synthesis and is required for DNA replication and genome stability during S phase. Inhibition of SET8 using shRNA results in arrest of replication forks, induction of double-stranded DNA breaks and a Chk1-mediated cell-cycle arrest in S and G2/M phases of the cell cycle. 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. Inhibition of SET8 using shRNA results in arrest of replication forks, induction of double-stranded DNA breaks and a Chk1-mediated cell-cycle arrest in S and G2/M phases of the cell cycle. Nucleosomes are preferred as substrate compared to free histones. Methylates p53K382, leading to repression of the pro-apoptotic and checkpoint activation functions of p53. SET8 expression levels decrease in response to DNA damage, allowing p53 to activate checkpoints and/or apoptosis. Both the methylation of histone H4K20 and p53K382 appear to be important for the functions of SET8 in S phase. Belongs to the histone-lysine methyltransferase family. PR/SET subfamily. Two isoforms of the human protein are produced by alternative splicing.

Product Notes
The SETD8 / PR-Set7 kmt5a (Catalog #AAA2545689) is a Recombinant Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. 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. Researchers should empirically determine the suitability of the SETD8 / PR-Set7 kmt5a for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "SETD8 / PR-Set7, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
