It's been a great couple of weeks for publications from the lab! First up we have a generalizable induced proximity system for gain of function PTM editing exemplified by acetylation and led by @briehp.bsky.social pubs.acs.org/acbcct/artic...

General Strategy for Controlling Functional Lysine Acetylation via Induced Proximity
AbstractAssigning causal function to post-translational modifications (PTMs) remains a central challenge in molecular biology, as most modification events

Beyond acetylation: Evaluating the emerging biology of lysine acylation
Lysine acylation is emerging as a fundamental mechanism linking cellular metabolism to protein regulation. Hintzen and Burslem synthesize the chemical biology, mechanistic principles, and unresolved questions that are redefining lysine acylation from an expanding catalog of modifications into a unifying framework for understanding metabolic regulation while outlining challenges.
