Post‐Translational Modifications in Animal Circadian Clocks
Circadian clocks coordinate physiology with daily environmental cycles through conserved transcriptional–translational feedback loops. This review summarizes how post‐translational modifications fine‐tune clock function, highlights the evolutionary convergence of circadian timekeeping in Drosophila and mammals, and emphasizes the central of these ...

Protease-activated receptor-2 (PAR2) is a G protein coupled receptor (GPCR) activated by proteolytic cleavage of its amino terminal domain by trypsin-like serine proteases. This irreversible activation mechanism leads to rapid receptor desensitization by

Summary: Ca2+-permeable AMPA-type glutamate receptors (CP-AMPARs) containing GluA1 but lacking GluA2 subunits contribute to multiple forms of synaptic plasticity, including long-term potentiation (LTP), but mechanisms regulating CP-AMPARs are poorly ...

Palmitoylation of Platelet Proteins
Palmitoylation as incorporation of [(3)H] palmitic acid into proteins occurred in platelets as in other cell systems. The linkage of palmitic acid to platelet proteins was stable to SDS and organic solvents but was sensitive to hydroxylamine, consistent with oxyester or thioester bond(s). Non-reduced SDS PAGE analysis revealed that the most prominantly

NLRP3, a cytosolic innate immune sensor, responds to diverse activators that perturb cellular homeostasis. These disturbances generate molecular scaffolds that, through binding partners such as nucleic acids, lipids, and proteins, recruit and concentrate NLRP3. Scaffold‐mediated NLRP3 clustering promotes NLRP3 inflammasome assembly.

Protein palmitoylation modification is a key lipidated post-translational modification that dynamically regulates protein function, subcellular localization, and signaling pathways in eukaryotic cells, with important implications for the onset and ...

In a kainic acid‐induced mouse model of epilepsy, upregulation of HSDL2 in the hippocampus prolonged seizure latency, increased the membrane expression of PSD95, and enhanced its phosphorylation. Concurrently, HSDL2 attenuated the interaction between PSD95 and the NMDAR subunits GluN2A/GluN2B, thereby suppressing NMDAR overactivation, reducing ...

The acyl‐CoA synthetase long‐chain (ACSL) family consists of five members, which exhibit a synergistic effect in promoting tumour lipid metabolism for energy supply. Specifically, ACSL3 and ACSL4 have antagonistic effects on the mechanisms related to ferroptosis in tumour cells.

Palmitoylation-dependent regulation of GPX4 suppresses ferroptosis
S-palmitoylation is a reversible and widespread post-translational modification, but its role in the regulation of ferroptosis has been poorly understood. Here, we elucidate that GPX4, an essential regulator of ferroptosis, is reversibly palmitoylated on
