Last paper post of the year!

Amazing Nature Chemical Biology paper by the group of Christina Woo. PCMT1 installs cyclic imides on asparagines at the C-terminus of proteins via SAM-dependent methyl ester formation, which then leads to degradation using cereblon.

An exciting new paper by researchers at Genentech led by Erin Dueber describes a ligase-agnostic #TargetedProteinDegradation platform based on direct 26S proteasome recruitment with macrocyclic PSMD2 ligands! Clever use of the D-enantiomeric macrocycle as an inactive control. These bifunctional ligands deliver target proteins to the 26S proteasome near the AAA+ unfoldase pore, bypassing the requirement for E3 ligase-mediated target ubiquitination prior to degradation!
