Cartoon illustrating our proposed pathway of HDAC reversibility to act as both a "writer" and "eraser" for protein acyl modifications

Thrilled to finally write up a little thread on our recent paper with @gburslem.bsky.social describing how HDACs reversibility contributes to protein lactylation!

Class I histone deacetylases catalyze lysine lactylation Metabolism and post-translational modifications (PTMs) are intrinsically linked and the number of identified metabolites that can covalently modify proteins continues to increase. This metabolism/PTM ...

New paper online from our long-standing collaboration with @dremilygoldberg.bsky.social on lysine lactylation catalysed by HDACs! www.jbc.org/article/S002...

A Potent Inhibitor of Caspase-8 Based on the IL-18 Tetrapeptide Sequence Reveals Shared Specificities between Inflammatory and Apoptotic Initiator Caspases Caspases are a family of cysteine proteases that act as molecular scissors to cleave substrates and regulate biological processes, such as programmed cell death and inflammation. Extensive efforts hav...

I’ve been many times and always leave feeling this way!

Juneteenth is a story of freedom hard-won & resilience hard-kept—honoring Black history & the ongoing fight for justice. At Penn Medicine, Research Trainee Affairs advances discovery rooted in respect, access & opportunity—values that shape our comprehensive education, training & outreach mission.

Truly grateful and honored to have had the opportunity to share my work at the Bioorganic GRC and represent the Burslem lab 💙

Congratulations to @briehp.bsky.social who gave an awesome Knowles award talk at the Bioorganic GRC! Very proud PI!

Feel free to reach out anytime!

Oh no! Sorry! We want people to read it but not at the expense of getting home! We’ll make sure to write less interesting papers from now on 🤣

Powerful protein editors offer new ways of probing living cells Scientists deploy self-splicing protein subunits to insert strange new additions into target proteins.

Trump Has Now Deported Multiple U.S. Citizen Children With Cancer Two families who had lived in the United States for years, including a child with cancer and a pregnant mother, were deported by ICE on Friday.

Honestly, if there is just one article that you are going to share far-and-wide today, it's this one:

'Trump Has Now Deported Multiple U.S. Citizen Children With Cancer'

The headline says it all, and everyone needs to know about this.

Thrilled to see our work now in @cp-molcell.bsky.social! It was an incredible privilege to do my postdoc with @ophirshalem.bsky.social and work alongside the super talented Steph Sansbury and our amazing co-authors. Excited to keep building on this research in our new lab at @rwjms.bsky.social!

Pooled tagging and hydrophobic targeting of endogenous proteins for unbiased mapping of unfolded protein responses Sansbury and Serebrenik et al. use pooled gene tagging with in situ sequencing and high-throughput image analysis to generate a cell pool with endogenous HaloTag fusions. Hydrophobic targeting is then...

Check out our paper, now extensively revised and published in @cp-molcell.bsky.social! This has been a real tour de force led by Stephanie Sansbury and @ysereb.bsky.social and we are very excited about the findings and future potential of this approach
