Anti-Phospho-Dnmt1(Ser714) Antibody

产品说明

一般描述

Methylation of DNA at cytosine residues plays an important role in regulation of gene expression, genomic imprinting and is essential for mammalian development. Hypermethylation of CpG islands in tumor suppressor genes may be linked with development of cancer. Three families of mammalian DNA methyltransferase genes have been identified which include Dnmt1, Dnmt2 and Dnmt3. Dnmt1 is constitutively expressed in proliferating cells and inactivation of Dnmt1 causes global demethylation of genomic DNA and embryonic lethality. Dnmt1 co-purifies with the retinoblastoma (Rb) tumour suppressor gene product, E2F1, and HDAC1. Dnmt1 also cooperates with Rb to repress transcription from promoters containing E2F binding sites suggesting a link between DNA methylation, histone deacetylase and sequence-specific DNA binding activity, as well as a growth-regulatory pathway that is disrupted in nearly all cancer cells. Phosphorylation of Ser714 is induced by EGF, but the role of this modification is unknown.

特异性

Not tested in other species.
This antibody recognizes human Dnmt1 phosphorylated on Ser714.

免疫原

Epitope: Ser714
The immunogen was a KLH-conjugated synthetic phosphopeptide corresponding to amino acid residues surrounding Ser714 of human Dnmt1.

应用

ELISA:
This antibody has been shown by an outside laboratory to be suitable for ELISA (1:1000).

Dot blotting:
This antibody has been shown by an outside laboratory to be specific for the phospho-Ser714 immunogen peptide, but not the unphosphorylated peptide, by dot blotting (1:500).
