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 -
Isoforms & Post-Translational Modification
P26358 has 3 isomers: P26358-1: 183165 Da (predicted); P26358-2: 184819 Da (predicted); P26358-3: 144465 Da (predicted).
Sumoylated; sumoylation increases activity;Acetylation on multiple lysines, mainly by KAT2B/PCAF, regulates cell cycle G(2)/M transition. Deacetylation of Lys-1349 and Lys-1415 by SIRT1 increases methyltransferase activity;Phosphorylation of Ser-154 by CDKs is important for enzymatic activity and protein stability. Phosphorylation of Ser-143 by AKT1 prevents methylation by SETD7 thereby increasing DNMT1 stability;Methylation at Lys-142 by SETD7 is necessary for the regulation of DNMT1 proteasomal degradation;Ubiquitinated by UHRF1; interaction with USP7 counteracts ubiquitination by UHRF1 by promoting deubiquitination and preventing degradation by the proteasome -
