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...

ProteomicsThe METTL5-TRMT112 N6-methyladenosine methyltransferase complex regulates metabolism and development via translation (Identification of m1A mRNA methyltransferase in nucleus by TMT11-LC-MS/MS)
m1A has long been known to be important in tRNA and rRNA, but we recently mapped many m1A sites in mRNA as well. m1A is found on the 5’ ends of genes, usually around the first splice site, but we have yet to understand how it effects transcript fate. Identifying the methyltransferase would be a ma...

TranscriptomicsA methyltransferase EHMT1 controls brown adipose cell fate and adaptive thermogenesis through a PRDM16 complex
Brown adipose tissue (BAT) dissipates chemical energy in the form of heat, as a defense against hypothermia and obesity. Current evidence indicates that brown adipocytes arise from Myf5+-dermotomal precursors through the action of a PRDM16-C/EBP-_ transcriptional complex; however, the underlying mec...

TranscriptomicsIdentification and Characterization of the Mammalian Nuclear RNA N6-Adenosine Methyltransferase Core Complex
N6-methyladenosine (m6A) is the most prevalent internal modification found in mammalian messenger and non-coding RNAs. The discoveries of functionally significant demethylases that reverse this methylation as well as the recently revealed m6A distributions in mammalian transcriptomes strongly indica...

ProteomicsAged Mouse Muscle: Sedentary or Exercised Animals with or without Nicotinamide N-methyltransferase Inhibitor Treatment
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...

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...

TranscriptomicsThe MOF-containing NSL complex associates globally with housekeeping genes, but activates only a defined subset (ChIP)
The MOF-containing NSL complex binds to many but not all promoters of active genes and potentially contributes to their proper gene expression. It is currently unknown what determines whether an active gene is bound or not. Here, we provide evidence that the NSL complex primarily targets active prom...

ProteomicsSkeletal muscle-specific methyltransferase METTL21C trimethylates p97 and regulates autophagy-associated protein breakdown
Protein aggregates and cytoplasmic vacuolization are major hallmarks of multisystem proteinopathies (MSP) that lead to muscle weakness. Here, we identify METTL21C as a novel skeletal muscle-specific lysine methyltransferase. Insertion of a -galactosidase cassette into the Mettl21c mouse locus reveal...

Protein arginine methyltransferase-6 (PRMT6) regulates steroid-dependent transcription and alternative splicing, and is implicated in endocrine system development and function, cell death, cell cycle, gene expression and cancer. Despite its role in these processes, little is known about its function...

ProteomicsMethyltransferase-like 3 (METTL3) regulates exocytosis
RNA modification pathways are often mis-regulated in various typers of cancer, with N6-methyladenosine (m6A) playing a pivotal role in cancer progression and metastasis. Methyltransferase-like 3 (METTL3), a core component of the m6A methyltransferase complex, functions not only as an m6A writer but ...
