Site-selective protein-modification chemistry for basic biology and drug development. [PDF]

, 2015
Nature has produced intricate machinery to covalently diversify the structure of proteins after their synthesis in the ribosome. In an attempt to mimic nature, chemists have developed a large set of reactions that enable post-expression modification of ...

Transcription factor LSF facilitiates lysine methylation of α-tubulin by microtubule-associated SET8 [PDF]

, 2019
Microtubules are critical for mitosis, cell motility, and protein and organelle transport, and are a validated target for anticancer drugs. However, tubulin regulation and recruitment in these cellular processes is less understood.

Norepinephrine Induces Sertoli Cell Ferroptosis via Receptors Desensitization Causing Stress‐Related Male Reproductive Dysfunction

Advanced Science, EarlyView.
Psychological stress activates the sympathetic–adrenal axis, elevating norepinephrine (NE) and suppressing reproductive hormones, thereby impairing male reproduction. Excess NE overactivates and desensitizes β‐adrenergic receptors (β‐ARs), triggering Sertoli cell ferroptosis and disrupting spermatogenesis.

Lactylation of HMGB1 at K177 Drives Nuclear Export of TIAR to Promote Hypoxia‐Induced Stress Granule Formation

Advanced Science, EarlyView.
This study uncovers a novel mechanism in which p300‑catalyzed lactylation of HMGB1 triggers nuclear export of the HMGB1‐TIAR complex, driving TIAR‐dependent SGs formation in the cytoplasm. Mass spectrometry and mutagenesis reveals that K177 lactylation is essential for this export and subsequent SGs formation.

SIRT6 Lysine‐Demyristoylates ATF2 to Ameliorate Vascular Injury via PRKCD/VE‐Cadherin Pathway Regulating Vascular Endothelial Barrier

Advanced Science, EarlyView.
A novel modified SIRT6 variant (dSIRT6) H133Y‐mediated enrichment technique unmasks 15 new human lysine‐myristoylated proteins. Notably, Sirtuin 6 (SIRT6) demyristoylation of activating transcription factor 2 (ATF2) at K296 orchestrates its nucleoplasmic translocation.

BLOC1S1 Attenuates B. Melitensis 16M LPS‐Triggered Autophagy by Spatial Confinement of TDP‐43

Advanced Science, EarlyView.
This study explores how B. melitensis 16M LPS and BLOC1S1 regulate autophagy in goat spermatogonial stem cells. The 16M LPS is activating AMPK‐dependent autophagy, increasing LC3B‐II/I ratios and lysosomal genes, while Escherichia coli LPS shows no effect.

PSMD14‐Mediated LDHA Deubiquitination Upregulates ACLY Expression via H3K18 Lactylation to Promote Lipid Synthesis and Pancreatic Cancer Progression

Advanced Science, EarlyView.
This study investigates the expression and functional role of the deubiquitinase PSMD14 in PC, with a focus on the mechanism by which it promotes lactate accumulation–induced histone lactylation, thereby driving aberrant lipid metabolism. These findings establish that dual targeting of PSMD14 and the glycolysis–lactylation signaling axis may represent ...

Post‐Translational Modifications of TOE3 Regulate Antiviral Defense in Tobacco

Advanced Science, EarlyView.
CK2αL phosphorylates TOE3 and enhances its stability, while FBXL1 promotes the ubiquitination‐degradation of TOE3 via the 26S proteasome. Compared to CK2αL‐phosphorylated TOE3, nonphosphorylated TOE3 shows a much higher affinity for FBXL1 and is more susceptible to ubiquitination‐degradation, thus facilitating viral infection. The regulatory mechanisms
