General description

DNMT1 (DNA (cytosine-5-)-methyltransferase 1) is mainly responsible for the DNA methyltransferase activity during replication. It is composed of CXXC region (C is cysteine; X is any amino acid), tandem bromo-adjacent homology (BAH1/2) and methyltransferase domains.

Immunogen

DNA (cytosine-5)-methyltransferase 1 recombinant protein epitope signature tag (PrEST)

Application

Anti-DNMT1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

Biochem/physiol Actions

DNMT1 (DNA (cytosine-5-)-methyltransferase 1) is involved in the maintenance of methylation in somatic cells. During DNA methylation, DNMT1 helps to form the correct pattern of DNA strand by arranging heterochromatin. The CXXC region shows higher binding affinity for unmethylated DNA compare to the hemimethylated or methylated DNA. By binding to the CpG dinucleotide, it hypermethylates CpG islands as well as helps in silencing of tumor suppressor genes. Alteration in DNMT1 activity leads to various human diseases such as cancer and genetic disorders.

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.

DNA methylation is an important epigenetic mechanism that ensures correct gene expression and maintains genetic stability. DNA methyltransferase 1 (DNMT1) is the primary enzyme that maintains DNA methylation during replication. Dysregulation of DNMT1 is implicated in a variety of diseases....

DNA methylation is regulated by hypoxia in endometriosis. Hypoxia causes global hypomethylation through AU-rich element binding factor 1 (AUF1)/microRNA-148a (miR-148a)-mediated destabilization of DNA methyltransferase 1 (DNMT1) mRNA. Eutopic endometrial and ectopic endometriotic stromal cells have the same genetic background, but...

Maintenance of genomic methylation patterns is mediated primarily by DNA methyltransferase-1 (DNMT1). We have solved structures of mouse and human DNMT1 composed of CXXC, tandem bromo-adjacent homology (BAH1/2), and methyltransferase domains bound to DNA-containing unmethylated CpG sites. The CXXC specifically...
