DNMT3L

DNMT3L

A gene on chromosome 21q22.3 that encodes a nuclear protein with similarity to DNA methyltransferases, which is not thought to function as a DNA methyltransferase, as it lacks the amino acid residues needed for methyltransferase activity, but does stimulate de novo methylation by DNA cytosine methyltransferase 3 alpha and is required for establishing maternal genomic imprints. It also mediates transcriptional repression by interacting with histone deacetylase 1.

Two hundred seventy-seven SNPs (single-nucleotide polymorphisms) within the range of 20 kb up- or downstream of the following genes were genotyped: DNMT1, DNMT3A, DNMT3B, DNMT3L, TET1, TET2, TET3, TDG using the Illumina HumanHap550, HumanHap550-Duo or Human610-Quad BeadChip microarrays as described previously (Torgerson et al.
We estimated the associations between variants in eight genes: DNMT1, DNMT3A, DNMT3B, DNMT3L, TET1, TET2, TET3, and TDG, and LINE1 and AluYb8 methylation using linear regression models described above.
Because genetic variation in methyl transferase and demethylases may directly alter the dynamic processes of methylation, we further investigated whether 262 SNPs in or near DNMT1, DNMT3A, DNMT3B, DNMT3L, TET1, TET2, TET3, and TDG altered the associations between first-trimester air pollutants and LINE1 methylation.
Histone H3K4 methylation may be a key involved in this process, because histone H3K4 methylation blocks the association of DNMT3L with the N-terminal of hisone H3, thus preventing the DNMT3A-DNMT3L complexes from accessing DNA.
2007) DNMT3L connects unmethylated lysine 4 of histone H3 to de novo methylation of DNA.
However, DNMT3L is a protein that is closely related to DNMT3A and DNMT3B structurally and is critical for DNA methylation, but appears to be inactive.
15,16) DNMT3L is highly expressed in gametes and is a known factor responsible for the acquisition of imprints during gametogenesis.
DNA methylation analysis of the DNMT3L promoter was carried out using the sodium bisulfite-assisted genomic DNA conversion method described previously by Gokul et al (18) Briefly, 1 mg of genomic DNA was denatured and mixed with low-melting agarose (BMA, Rockland, Maine) and pipetted into cold, heavy mineral oil (Sigma-Aldrich, St Louis, Missouri) to form beads.
We analyzed the methylation pattern of DNMT3A, DNMT3B and DNMT3L genes and its association with RUNX3 methylation pattern, in Brazilian samples of gastric adenocarcinoma intestinal-type and Lauren diffuse-type (Lauren, 1965).
DNMT3 family is composed by DNMT3A, DNMT3B and DNMT3L located, respectively, at 2p23, 20q11.
FIT Biotech has also built an impressive intellectual property portfolio and has filed numerous international patents for its technology and the applications based on it, including novel vectors (GTU), medical devices (device and gene therapy), self-replicating vectors for DNA immunization against HIV, AIRE (immunological mechanisms) and DNMT3L (immune diseases, new genes).
