Macrophage‐derived MLKL in alcohol‐associated liver disease: Regulation of phagocytosis

Hepatology, EarlyView., 2022
EtOH causes leaky gut allowing bacteria and PAMPs into the liver, resulting in hepatic inflammation and injury. We demonstrate that LPS induces STAT1‐mediated expression and phosphorylation of MLKL in macrophages and identify a novel function that myeloid MLKL translocates to phagosomes and lysosomes and regulates phagocytosis, which contributes to the

Nucleotide based covalent inhibitors of KRas can only be efficient in vivo if they bind reversibly with GTP-like affinity

Scientific Reports, 2017
Simple reversible competitive inhibition of nucleotide binding of GTP to Ras family GTPases has long been recognized as an unlikely approach to manipulating the activity of such proteins for experimental or therapeutic purposes.

Structural basis of mitochondrial receptor binding and constriction by DRP1. [PDF]

, 2018
Mitochondrial inheritance, genome maintenance and metabolic adaptation depend on organelle fission by dynamin-related protein 1 (DRP1) and its mitochondrial receptors. DRP1 receptors include the paralogues mitochondrial dynamics proteins of 49 and 51 kDa

Mechanical Cues Regulate Cargo Sorting and Export at the Golgi

Advanced Science, EarlyView.
A pathway is identified linking extracellular matrix stiffness to secretion via Src–FAK–AMPK–GBF1 signaling. Golgi‐localized GBF1 acts as a mechanotransducer whose phosphorylation controls post‐Golgi cargo sorting toward secretion or lysosomal degradation.

Adenylosuccinate Synthase 1 Deficiency Improves Energy Metabolism by Promoting Adipose Tissue Re‐esterification via Glycerol Kinase Upregulation

Advanced Science, EarlyView.
Working model of Adss1‐mediated regulation of energy metabolism in adipose tissue. In beige adipocytes, Adss1 interacts with HDAC3 in the cytoplasm, and its loss reduces nuclear HDAC3 while increasing cytosolic fractions. This redistribution suppresses HDAC activity and enhances H3K27 acetylation at the Gk promoter, leading to transcriptional ...

Functional significance may underlie the taxonomic utility of single amino acid substitutions in conserved proteins [PDF]

, 2010
We hypothesized that some amino acid substitutions in conserved proteins that are strongly fixed by critical functional roles would show lineage-specific distributions.

Gigaxonin Potentiates Antiviral Innate Immune Responses by Targeting cGAS and TREX1

Advanced Science, EarlyView.
TREX1 antagonizes DNA sensor cGAS by degrading cytosolic DNA. This work identifies gigaxonin as a molecular switch that coordinates DNA sensing and clearance pathways to amplify antiviral responses. Under the steady state, gigaxonin maintains cellular homeostasis by mediating TREX1 ubiquitination and proteasomal degradation. During DNA virus infection,

Protein Secretion and GTP-binding Proteins.

Seibutsu Butsuri, 1991
GTP-binding proteins are involved in a wide variety of cellular functions. One of the most recent findings is the implication of many GTP-binding proteins in the pathway of protein secretion. In the eukaryotic secretory pathway, proteins have to be sorted from each other at many steps, including the signal recognition and translocation across the ...
