DNA (cytosine-5)-methyltransferase 1 is an enzyme that in humans is encoded by the DNMT1 gene.^[1]

DNA (cytosine-5-)-methyltransferase 1 has a role in the establishment and regulation of tissue-specific patterns of methylated cytosine residues. Aberrant methylation patterns are associated with certain human tumors and developmental abnormalities.^[2]^[3]

Interactions

DNMT1 has been shown to interact with Histone deacetylase 2,^[4] DMAP1,^[4] PCNA,^[4]^[5]^[6] Retinoblastoma protein,^[7] DNMT3A^[8] and DNMT3B.^[8]^[9]
