Data suggest that, upon HIV-1 infection, DNMT2 is re-localized from the nucleus to cytoplasmic stress granules where DNMT2 methylates HIV-1 messenger RNA; this methylation increases the stability of the HIV-1 RNA genome and up-regulates virus replication; thus, DNMT2 appears to facilitate HIV-1 infection. PMID: 28476776
The strong effect of some of the somatic cancer mutations on DNMT2 activity suggests that these mutations have a functional role in tumorigenesis. PMID: 25747896
Mapped is the tRNA binding site of DNMT2 by systematically mutating surface-exposed lysine and arginine residues to alanine and studying the tRNA methylation activity and binding of the corresponding variants. PMID: 22591353
the role of Dnmt2 in stress granules could represent a primitive cellular defense mechanism against viral infection. PMID: 20864816
identification of residual DNA-(cytosine-C5) methyltransferase activity PMID: 12794065
cDNA microarray analysis identified several genes involved in DNA methylation, such as DNMT2 and DNMT3a that were more highly expressed in LNCaP-r (an androgen sensitive prostate cancer cell line). PMID: 16173030
genetic and biochemical approach revealed that DNMT2 did not methylate DNA but instead methylated aspartic acid transfer RNA (tRNA(Asp)) and that DNMT2 specifically methylated cytosine 38 in the anticodon loop PMID: 16424344
