This dataset corresponds to an intact mass spectrometry study focusing on the covalent binding interaction between purified FGFR2 V564F protein and compound LC-F2-1. The purified FGFR2 V564F was adjusted to 28 μM, then incubated with LC-F2-1 at molar ratios of 1:2 or 1:5 for 4 hours at room temperat...

Here we present an approach for the mapping of unmethylated DNA. Our technique is based on DNA methyltransferase-directed transfer of activated groups (mTAG) and covalent biotin tagging of unmodified CpG sites followed by affinity enrichment and interogation on tiling microarrays or next generation ...

Engineering covalent small molecule–RNA complexes in living cells
Cyclin-dependent kinase 7 (CDK7) plays a critical role in the general regulation of RNA polymerase II-mediated transcription. However, the absence of selective CDK7 inhibitors has hindered the ability to investigate the consequences of acute and prolonged inhibition of CDK7 under normal and patholo...

Covalent Targeting of Splicing in T Cells
The αIIbβ3 integrin receptor coordinates platelet adhesion, activation and mechanosensing in thrombosis and haemostasis. Using differential cysteine alkylation and mass spectrometry, we have identified a disulfide bond in the αIIb subunit linking cysteines 490 and 545 that is missing in about one in...

Alanyl-tRNA synthetase 1 (AARS1) was recently identified as a lactyltransferase responsible for protein lactylation, a modification associated with epigenetic regulation and metabolic adaptation. AARS1 catalyzes lysine lactylation via an ATP- and lactate- dependent, but lactyl-CoA-independent mechan...
