Kinetically Stable Boron‐Heteroatom Bonds
Angewandte Chemie, EarlyView.This study investigates the kinetic stability of boron‐heteroatom bonds in N‐methyliminodiacetic acid (MIDA) boronates. The hemilabile nature of the ligand enables the synthesis of molecules that would otherwise be considered too hydrolytically labile. Depending on the structure, acid‐promoted migration of the boryl group was found to produce compounds

Stearic acid blunts growth-factor signaling via oleoylation of GNAI proteins
Nature Communications, 2021 S-acylation is the post-translational covalent attachment of fatty acids (FA) onto cysteines. Nuskova et al. find that exposure of cells to different FAs affects which FA is used to S-acylate GNAI proteins, thereby altering GNAI function and EGFR pathway

Detection of S-Acylated CD95 by Acyl-Biotin Exchange [PDF]
, 2017 S-acylation is the covalent addition of a fatty acid, most generally palmitate onto cysteine residues of proteins through a labile thioester linkage. The death receptor CD95 is S-palmitoylated and this post-translational modification plays a crucial role on CD95 organization in cellular membranes and thus on CD95-mediated signaling.

Therapeutic targeting of protein S-acylation for the treatment of disease [PDF]
Biochemical Society Transactions, 2019 The post-translational modification protein S-acylation (commonly known as palmitoylation) plays a critical role in regulating a wide range of biological processes including cell growth, cardiac contractility, synaptic plasticity, endocytosis, vesicle trafficking, membrane transport and biased-receptor signalling.

Advanced Science, EarlyView.This study reveals a metabolic signaling axis in the OSCC microenvironment where palmitic acid (PA) drives the activation of CAFs. PA uptake triggers CEBPG‐dependent epigenetic remodeling to upregulate ERN1 and TMBIM6, thereby mitigating ER stress. This adaptive program sustains CAF survival and the pro‐metastatic phenotype, establishing this pathway ...

Glutathione‐Responsive Acyl‐Modifications for Targeted RNA Decaging and Prolonged Protein Synthesis
Angewandte Chemie, EarlyView.The self‐immolation of disulfide‐based mRNA modifications in response to endogenous glutathione (GSH) promotes a gradual release of translatable mRNA within the cell, leading to improved nuclease resistance, tunable release properties, and a significant increase (up to 600%) of target protein production over time. This strategy offers an exciting proof

Ion channel regulation by protein S-acylation [PDF]
Journal of General Physiology, 2014 Protein S-acylation, the reversible covalent fatty-acid modification of cysteine residues, has emerged as a dynamic posttranslational modification (PTM) that controls the diversity, life cycle, and physiological function of numerous ligand- and voltage-gated ion channels.

Advanced Science, EarlyView.The TPR‐LYTACs nanomaterial offers a dual‐pathway strategy for precise gouty arthritis treatment by targeting and degrading the ROS‐producing enzyme NOX2 inside macrophages while its antioxidant core clears accumulated ROS outside. This “source inhibition and microenvironment scavenging” approach, guided by NIR‐II imaging, effectively controls local ...

Acylation – A New Means to Control Traffic Through the Golgi
Frontiers in Cell and Developmental Biology, 2019 The Golgi is well known to act as center for modification and sorting of proteins for secretion and delivery to other organelles. A key sorting step occurs at the trans-Golgi network and is mediated by protein adapters. However, recent data indicate that
