KRAS/ABHD17C/ALOX15B Axis Promotes Pancreatic Cancer Progression via Ferroptosis Evasion. [PDF]
Phosphorylation of ABHD17C induced by KRASmut/ERK signaling facilitates ALOX15B depalmitoylation and degradation via the CUL4/DDB1/DCAF10 complex, thereby enabling KRASmut‐PDAC cell to evade ferroptosis. Methyl protodioscin inhibits KRASmut‐PDAC progression by disrupting the ABHD17C/ALOX15B interaction and inducing ferroptosis, which represents a ...

FKBP12 Binds to Acylated H-Ras and Promotes Depalmitoylation [PDF]
A cycle of palmitoylation/depalmitoylation of H-Ras mediates bidirectional trafficking between the Golgi apparatus and the plasma membrane, but nothing is known about how this cycle is regulated. We show that the prolyl isomerase (PI) FKBP12 binds to H-Ras in a palmitoylation-dependent fashion and promotes depalmitoylation.

Cardiac sodium channel palmitoylation regulates channel availability and myocyte excitability with implications for arrhythmia generation [PDF]
Cardiac voltage-gated sodium channels (Nav1.5) play an essential role in regulating cardiac electric activity by initiating and propagating action potentials in the heart.

A fluorescent probe for cysteine depalmitoylation reveals dynamic APT signaling [PDF]
Hundreds of human proteins are modified by reversible palmitoylation of cysteine residues (S-palmitoylation), but the regulation of depalmitoylation is poorly understood. Here, we develop 'depalmitoylation probes' (DPPs), small-molecule fluorophores, to monitor the endogenous activity levels of 'erasers' of S-palmitoylation, acylprotein thioesterases ...

Palmitoylated ras proteins traffic through recycling endosomes to the plasma membrane during exocytosis [PDF]
Ras proteins regulate cell growth, death, and differentiation, and it is well established that this functional versatility is accomplished through their different subcellular localizations.

Depalmitoylation of Ykt6 Prevents its Entry into the Multivesicular Body Pathway [PDF]
The dually lipidated SNARE Ykt6 is found on intracellular membranes and in the cytosol. In this study, we show that Ykt6 localizes to the Golgi as well as endosomal and vacuolar membranes in vivo. The ability of Ykt6 to cycle between the cytosol and the membranes depends on the intramolecular interaction of the N‐terminal longin and C‐terminal SNARE ...

ATP-independent Control of Vac8 Palmitoylation by a SNARE Subcomplex on Yeast Vacuoles [PDF]
Yeast vacuole fusion requires palmitoylated Vac8. We previously showed that Vac8 acylation occurs early in the fusion reaction, is blocked by antibodies against Sec18 (yeast N-ethylmaleimide-sensitive fusion protein (NSF)), and is mediated by the R-SNARE

Cellular signaling and NO production [PDF]
The endothelium can evoke relaxations (dilatations) of the underlying vascular smooth muscle, by releasing vasodilator substances. The best characterized endothelium-derived relaxing factor is nitric oxide (NO), which is synthesized by the endothelial ...

Role of Palmitoylation of Postsynaptic Proteins in Promoting Synaptic Plasticity
Many postsynaptic proteins undergo palmitoylation, the reversible attachment of the fatty acid palmitate to cysteine residues, which influences trafficking, localization, and protein interaction dynamics.
