The UniProt recommended name is DNA (cytosine-5)-methyltransferase 3A (DNMT3A). This nuclear enzyme catalyzes the transfer of a methyl group to the 5-position of cytosine residues within CpG dinucleotides, a key mechanism of epigenetic gene regulation.\u003cbr\u003e\u003cbr\u003eFunctionally, DNMT3A antibody identifies an 912-amino-acid methyltransferase that functions together with DNMT3B and DNMT3L to establish DNA methylation marks during embryogenesis. DNMT3A binds chromatin through its PWWP domain and ADD (ATRX-DNMT3-DNMT3L) domain, recognizing histone modifications that guide locus-specific methylation. By controlling methylation of promoters, enhancers, and repetitive elements, DNMT3A ensures stable gene silencing and genome integrity.\u003cbr\u003e\u003cbr\u003eThe DNMT3A gene is located on chromosome 2p23.3 and is highly expressed in stem cells, germ cells, and hematopoietic progenitors. Expression decreases during differentiation, consistent with its role in developmental programming. DNMT3A activity is essential for imprinting, X-chromosome inactivation, and transposon silencing.\u003cbr\u003e\u003cbr\u003ePathologically, mutations in DNMT3A are among the most common in acute myeloid leukemia (AML), myelodysplastic syndromes, and clonal hematopoiesis. Loss-of-function mutations impair methylation fidelity, causing epigenetic instability and aberrant gene expression. Germline mutations lead to Tatton-Brown-Rahman syndrome, characterized by overgrowth and intellectual disability. Research using DNMT3A antibody supports studies in epigenetics, cancer biology, and developmental regulation.\u003cbr\u003e\u003cbr\u003eDNMT3A antibody is validated for western blotting, immunofluorescence, and chromatin immunoprecipitation to detect DNA methyltransferases. \u003cbr\u003e\u003cbr\u003eStructurally, DNA (cytosine-5)-methyltransferase 3A consists of an N-terminal regulatory region containing the PWWP and ADD domains, and a C-terminal catalytic domain with the conserved PCQ motif required for methyl group transfer. DNMT3A forms complexes with DNMT3L to enhance DNA binding and catalytic efficiency. This antibody enables investigation of DNMT3A's function in epigenetic gene silencing and oncogenic transformation.\u003c\/div\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConnecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).\u003c\/li\u003e\n\u003cli\u003eConsidering isoforms and post-translational regulation when interpreting protein-level changes.\u003c\/li\u003e\n\u003cli\u003eComparing results across species and model systems with matched controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blotting:\u003c\/strong\u003e compare relative abundance and activation-state changes across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunofluorescence:\u003c\/strong\u003e visualize subcellular distribution and cell-to-cell heterogeneity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry:\u003c\/strong\u003e map target signal in tissue context and compare regions\/phenotypes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e quantify target-positive populations and signal shifts at single-cell resolution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eELISA:\u003c\/strong\u003e support antibody-based quantification in assay formats where applicable.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSignal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.\u003c\/li\u003e\n\u003cli\u003eSpecies differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAntibody notes:\u003c\/strong\u003e Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.\u003c\/p\u003e\u003c!-- Sources (internal): - UniProt search — UniProt — https:\/\/www.uniprot.org\/uniprotkb?query=DNMT3A - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=DNMT3A - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=DNMT3A - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/DNMT3A - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=DNMT3A+review --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"Adding 0.2 ml of distilled water will yield a concentration of 500 ug\/ml \/ 100 ug","offer_id":53047319855469,"sku":"FY13240","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_43482a21-9b15-48b8-9962-01eed0b41d98.jpg?v=1782237090","url":"https:\/\/www.ebiohippo.com\/products\/dnmt3a-antibody-dna-cytosine-5-methyltransferase-3a-bha17136142","provider":"BioHippo","version":"1.0","type":"link"}
