MetabolomicsMitochondrial KMT9 methylates DLAT to control pyruvate dehydrogenase activity and prostate cancer growth

Prostate cancer (PCa) growth depends on de novo lipogenesis controlled by the mitochondrial pyruvate dehydrogenase complex (PDC). In this study, we identified lysine methyltransferase (KMT)9 as a novel regulator of PDC activity. KMT9 is localized in mitochondria of PCa cells, but not in mitochond...

ProteomicsRPL40 methyltransferase discovery and characterisation
The eukaryotic ribosome is highly modified by protein methylation, yet many of the responsible methyltransferases remain unknown. Here we have identified SMYD5 as a ribosomal protein methyltransferase that catalyses trimethylation of RPL40 at lysine 22. Through a systematic mass spectrometry-based a...

ProteomicsQuantitative profiling of the enzymatic activity of the protein lysine mono-methyltransferase SMYD2 using SILAC-based proteomics
The significance of non-histone lysine methylation in cell biology and human disease is an emerging area of research exploration, and small molecule inhibitors that selectively and potently target “writers” and “erasers” of methyl-lysine, such as the protein lysine mono-methyltransferase SMYD2, are ...

GenomicsCpG underrepresentation and the new bacterial CpG specific DNA methyltransferase M.MpeI
The CpG depleted Mycoplasma penetrans harbors a CpG specific C5 methyltransferase. The aim of this experiment was to confirm the specificity of the methyltransferase in vivo and in vitro. Genomic DNA from Mycoplasma penetrans and Escherichia coli genomic DNA that either was or was not methylated in ...

TranscriptomicsSmall RNA mediated DNA (cytosine-5) methyltransferase 1 inhibition leads to aberrant DNA methylation
Mammalian cells contain copious amounts of RNA including both coding and non-coding RNA (ncRNA). Generally the ncRNAs function to regulate gene expression at the transcriptional and post-transcriptional level. Among ncRNA, the long ncRNA and small ncRNA can affect histone modification, DNA methylati...

ProteomicsGlutathionylation decreases methyltransferase activity of PRMT5 and inhibits cell proliferation
Glutathionylation is an important posttranslational modification that protects proteins from further oxidative damage as well as influencing protein structure and activity. In the present study, we demonstrate that the cysteine-42 residue in protein arginine N-methyltransferase 5 (PRMT5) is glutathi...

Aged (22-mo) female mice (n=35), obtained from the US NIH National Institute on Aging (NIA) Aged Rodent Colony, were randomly assigned to one of four groups: saline-treated sedentary ( n=9), nicotinamide N-methyltransferase inhibitor (NNMTi)-treated sedentary (10 mg/kg body weight; n=9), saline-trea...

GenomicsThe histone methyltransferase activity of MLL1 is dispensable for hematopoiesis and leukemogenesis
Despite correlations between histone methyltransferase (HMT) activity and gene regulation, direct evidence that HMT activity is responsible for gene activation is sparse. We address the role of the HMT activity for MLL1, a histone H3 lysine 4 (H3K4) methyltransferase critical for maintaining hematop...

GenomicsSplicing enhances recruitment of methyltransferase HYPB/Setd2 and methylation of histone H3 lysine 36
Several lines of recent evidence support a role for chromatin in splicing regulation. Here we show that splicing can also contribute to histone modification, which implies a bidirectional communication between epigenetics and RNA processing. Genome-wide analysis of histone methylation in human cell ...
