DNA Methyltransferase 3B (DNMT3B) Protein | DNMT3B protein
Eukaryotic DNA Methyltransferase 3B (DNMT3B)
20mM Tris, 150mM NaCl, pH8.0, containing 1mM EDTA, 1mM DTT, 0.01% SKL, 5% Trehalose and Proclin300.
Stable for 12 months if correctly stored.
The thermal stability is described by the loss rate. The loss rate was determinedby accelerated thermal degradation test, that is, incubate the protein at 37 degree C for 48h, and noobvious degradation and precipitation were observed. The loss rate is less than 5% within theexpiration date under appropriate storage condition.

NCBI and Uniprot Product Information
NCBI Description
CpG methylation is an epigenetic modification that is important for embryonic development, imprinting, and X-chromosome inactivation. Studies in mice have demonstrated that DNA methylation is required for mammalian development. This gene encodes a DNA methyltransferase which is thought to function in de novo methylation, rather than maintenance methylation. The protein localizes primarily to the nucleus and its expression is developmentally regulated. Mutations in this gene cause the immunodeficiency-centromeric instability-facial anomalies (ICF) syndrome. Eight alternatively spliced transcript variants have been described. The full length sequences of variants 4 and 5 have not been determined. [provided by RefSeq, May 2011]
Uniprot Description
DNMT3B: a ubiquitous DNA methyltransferase required for genome wide de novo methylation and essential for development. DNA methylation is coordinated with methylation of histones. Numerous cancer cell lines and primary acute leukemias express aberrant DNMT3B transcripts, especially DNMT3B7. Transfection of DNMT3B7 into 293 cells alters the pattern of genes expressed in the transfected cells. Can interact with DNMT1, which might be a co-operative event during DNA methylation. Methylates CpG sites at a rate slower than DNMT3A and much slower than DNMT1. Interacts with SUV39H1, SETDB1, SUMO1 and UBE2I9. Interacts with DNMT1 and DNMT3A. Mutations in DNMT3B have been shown to cause immunodeficiency-centromeric instability-facial anomalies syndrome (ICF). Six alternatively spliced isoforms of the human protein have been reported. Isoform 1 is expressed in all tissues except brain, skeletal muscle and PBMC, 3 is ubiquitous, 4 is expressed in all tissues except brain, skeletal muscle, lung and prostate and 5 is detectable only in testis and at very low level in brain and prostate. Isoforms 4 and 5 are probably not enzymatically active due to the deletion of two conserved methyltransferase motifs.

Product Notes
The DNMT3B dnmt3b (Catalog #AAA2125391) is a Protein produced from 293F Cell and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's DNA Methyltransferase 3B (DNMT3B) can be used in a range of immunoassay formats including, but not limited to, Positive Control, Immunogen, SDS-PAGE, Western Blot (WB). Researchers should empirically determine the suitability of the DNMT3B dnmt3b 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. The amino acid sequence is listed below: Ser145~Pro 355. It is sometimes possible for the material contained within the vial of "DNA Methyltransferase 3B (DNMT3B), 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
