Background:
Required for genome-wide de novo methylation and is essential for the establishment of DNA methylation patterns during development. DNA methylation is coordinated with methylation of histones. It modifies DNA in a non-processive manner and also methylates non-CpG sites. May preferentially methylate DNA linker between 2 nucleosomal cores and is inhibited by histone H1. Plays a role in paternal and maternal imprinting. Required for methylation of most imprinted loci in germ cells. Acts as a transcriptional corepressor for ZBTB18. Recruited to trimethylated 'Lys-36' of histone H3 (H3K36me3) sites. Can actively repress transcription through the recruitment of HDAC activity.
VALIDATION IMAGES
To determine the titer of the antibody, an ELISA was performed using a serial dilution of Bioss antibody directed against human DNMT3A (Cat. No. bs-53128R), crude serum and Flow Through, in antigen-coated wells. By plotting the absorbance against the antibody dilution, the titer of the antibody was estimated to be 1:500.
Human embryonic kidney cells (HEK293T) were transiently transfected with an expression vector for GAL4- tagged DNMT3A. Whole cell extracts were immunoprecipitated with 2 μg of DNMT3A Polyclonal Antibody (Cat. No. bs-53128R). The presence of GAL4-DNMT3A in the non-treated cell extracts and in the immunoprecipitates was demonstrated by western blot analysis with the anti-GAL4 antibody (lane 1 and 2 respectively). Alternatively, GAL4-DNMT3A was immunoprecipitated and western blot analysis was performed with the DNMT3A antibody (diluted 1:2,000) (lane 3).
