Regioselective rapid ene-type reaction (RRER) enables bioconjugation of histone serotonylation Triazolinedione (TAD) derivatives have been commonly utilized as protection and labeling reagents for indole and phenol moieties via a reversible ene-type reaction. Previous studies showed that the TA...

I am happy to share that we recently developed and named a pH-controlled regioselective rapid ene-type reaction as "RRER" for the specific bioconjugation of a novel epigenetic mark, histone serotonylation. It is now online @rscchembio.rsc.org pubs.rsc.org/en/content/a...

Bidirectional histone monoaminylation dynamics regulate neural rhythmicity - Nature TG2 functions as an eraser and exchanger of H3 monoaminylations, including histaminylation of Gln5 of histone H3.

Excited to see our paper out @nature.com In this work, we discovered that histone monoaminylation dynamics are regulated by a single enzyme (TGM2) and can promote neural rhythmicity by inhibiting the binding of WDR5 to H3 N-terminus.

pH-Controlled chemoselective rapid azo-coupling reaction (CRACR) enables global profiling of serotonylation proteome in cancer cells bioRxiv - the preprint server for biology, operated by Cold Spring Harbor Laboratory, a research and educational institution

Although serotonylation was discovered in the 1950s, a full picture of serotonylated proteins in cells is poorly understood. In this work, we applied pH-controlled CRACR (originally developed by @achemsynbio.bsky.social lab) for profiling serotonylation proteome. www.biorxiv.org/content/10.1...
