Background
DNMT3L is a nuclear DNA methyltransferase (DNMT)-like protein. DNMTs are a family of enzymes that catalyze the transfer of a methyl group to DNA, a covalent genomic modification mechanism has a wide range of biological functions. DNMTs are most well recognized for regulating and maintaining genomic imprinting, a germline-specific epigenetic genome process involving both DNA methylation and histone modifications. Imprinting results in certain genes being expressed in a parent-of-origin manner and is essential for normal development.
Three active DNMTs have been identified in mammals, DNMT1, DNMT3A and DNMT3B. However, DNMT3L lacks the amino acid residues necessary for methyltransferase activity and is catalytically inactive. Hence, DNMT3L cannot directly methylate DNA. Rather, DNMT3L is thought to function as a regulator of DNA methylation. For example, DNMT3L co-localizes with DNMT3a and DNMT3b in the nucleus and stimulates their activity through protein-protein interactions possibly by anchoring the DNMTs to the chromatin. DNMT3L is thought to be required for maternal genomic imprints and there is evidence that DNMT3L also mediates transcriptional repression through interaction with histone deacetylase 1. Dysregulation of DNMT3L has been associated with cancer, and hence DNMT3L may play an important role in aberrant gene expression during carcinogenesis through alteration of methylation patterns. |
Antigen
A portion of amino acids 25-75 from human Dnmt3L was used as the immunogen for this antibody.

Western blot analysis of Dnmt3L using Dnmt3L antibody. GST tagged full length recombinant Human Dnmt3L in the 1) pre immune sera and 2) abesence of immunizing peptide, probed with 2 ug/ml of Dnmt3L antibody. IMGENEX’s goat anti-rabbit Ig HRP secondary antibody (20301) and PicoTect ECL substrate solution (10087K) were used for this test. |
