Gene Information

human ... DNMT1(1786)

General description

In humans, the gene encodes a DNA (cytosine-5)-methyltransferase with 1616 amino acids. The N-terminal contains the regulatory domain, while the C-terminal region contains the catalytic domain. Two isoforms of DNMT1 have been isolated, DNMT1a and DNMT1b, the difference residing in 16 extra amino acids within the latter.

Immunogen

synthetic peptide corresponding to amino acids 72-78 of human DNMT1, conjugated to KLH via an N-terminal added cysteine residue. The sequence is conserved in mouse and is different from the rat sequence by one amino acid.

Application

Anti-DNMT1 antibody produced in rabbit is suitable for microarray and immunoblotting at a working concentration of 0.5-1.0μg/mL using nuclear extracts of 293T or HeLa cells. It was used at 1:1000 working dilution for immunoblot analysis in a study to analyze whether some miRNAs are aberrantly expressed and target DNMT1 in NiS (nickel sulfide)-transformed cells. It was used for immunoprecipitation of DNMT1 from nuclear lysates of colon cancer cells transfected with DNMT1 vectors in a study. It was used as a primary antibody at a working dilution of 1:1000 for western blot analysis of total protein extracted from left murine testis tissue exposed to low-dose-rate radiation in a study.
Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.

Western Blotting (1 paper)

Biochem/physiol Actions

DNMT1 protein is important for the maintenance of methylation, as well as for the novo methylation activities occurring in somatic cells of vertebrates. It establishes a repressive transcription complex at replication foci with histone deacetylase HDAAC4 and DMAP1.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin and 15 mM sodium azide.

This study examined the effects of continuous low-dose-rate radiation exposure (3.49 mGy/h) of gamma rays on mice testicles. C57BL/6 mice were divided into sham and radiation groups (n = 8 each), and were exposed to either sham irradiation or 2...

Downregulation of microRNA‑152 (miR‑152) has been observed in various types of human malignancies, including Bladder cancer (BC). However, the role of miR‑152 in the development and progression of BC is still unclear. In our previous study, we identified a functional...

Nickel (Ni) compounds are well-recognized human carcinogens, yet the molecular mechanisms by which they cause human cancer are still not well understood. MicroRNAs (miRNAs), which are small non-coding RNAs, are involved in diverse biological functions and carcinogenesis. In previous study...

Hypermethylation is associated with the silencing of tumour susceptibility genes in several forms of cancer; however, the mechanisms responsible for this aberrant methylation are poorly understood. The prototypic DNA methyltransferase, DNMT1, has been widely assumed to be responsible for most...

Combining DNA-demethylating agents (DNA methyltransferase inhibitors [DNMTis]) with histone deacetylase inhibitors (HDACis) holds promise for enhancing cancer immune therapy. Herein, pharmacologic and isoform specificity of HDACis are investigated to guide their addition to a DNMTi, thus devising a new, low-dose...
