Western blot analysis of extracts from HEK293(lane2(20μg) , HepG2(lane 3(20μg) and C6(lane 4(20ug) using Dnmt1 Antibody (HY-P80106) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.

Immunocytochemistry analysis of HeLa cells labeling Dnmt1 with Dnmt1 Antibody (HY-P80106 )at 1/50 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 for 10 minutes at room temperature, then blocked with QuickBlock™ Blocking Buffer for Immunol Staining for 10 min at room temperature. Cells were then incubated with LOX1 Antibody (HY-P80106 ) at 1/50 dilution in QuickBlock™ Blocking Buffer for Immunol Staining at 4 ℃. Alexa Fluor® 488-conjugated AffiniPure Goat Anti-Rabbit IgG H&L(HY-P8002, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

Background

Function
DNMT1 (DNA methyltransferase 1) is the principal maintenance DNA methyltransferase that preferentially recognizes hemimethylated CpG sites and preserves DNA methylation patterns during DNA replication, thereby supporting epigenetic inheritance and stable gene regulation[1][2]. Mechanistically, DNMT1 functions within the DNA methylation machinery that maintains chromatin states, transcriptional programs, and genome stability, and its recruitment to newly replicated DNA is coordinated by factors such as UHRF1[1][3]. Through maintenance of CpG methylation, DNMT1 contributes to developmental processes, cellular identity, and long-term repression of transposable elements[1][4]. In disease contexts, aberrant DNMT1 activity is strongly associated with cancer, where sustained DNA methylation can promote silencing of tumor-suppressor genes and support malignant phenotypes[1][5][6]. Experimental studies further demonstrate that selective depletion of DNMT1 induces global and gene-specific demethylation and reactivates silenced tumor-suppressor genes in human cancer cells, highlighting its central role in epigenetic regulation[6]. Compared with the related de novo methyltransferases DNMT3A and DNMT3B, which establish new methylation patterns, DNMT1 primarily propagates existing methylation marks after DNA replication, although recent evidence indicates that DNMT1 can also exhibit context-dependent de novo methylation activity, particularly at retrotransposon loci[4]. For experimental applications, DNMT1 remains a major epigenetic drug target, and both nucleoside-based and emerging selective non-nucleoside inhibitors are widely used to investigate DNA methylation dynamics and therapeutic reprogramming of aberrant epigenetic states[5].

Expression
Tissue_specificity:Ubiquitous; highly expressed in fetal tissues, heart, kidney, placenta, peripheral blood mononuclear cells, and expressed at lower levels in spleen, lung, brain, small intestine, colon, liver, and skeletal muscle. Isoform 2 is less expressed than isoform 1
Induction:Its abundance is reduced to non detectable levels at the G0 phase of the cell cycle and is dramatically induced upon entrance into the S-phase of the cell cycle -
Subunit
Homodimer (PubMed:19173286). Forms a stable complex with E2F1, BB1 and HDAC1 (PubMed:10888886). Forms a complex with DMAP1 and HDAC2, with direct interaction (PubMed:10888872).
