Impaired nutrient signaling and body weight control in a Na⁺ neutral amino acid cotransporter (Slc6a19)-deficient mouse [PDF]
Amino acid uptake in the intestine and kidney is mediated by a variety of amino acid transporters. To understand the role of epithelial neutral amino acid uptake in whole body homeostasis, we analyzed mice lacking the apical broad-spectrum neutral (0 ...

GPNA inhibits the sodium-independent transport system l for neutral amino acids
L-γ-Glutamyl-p-nitroanilide (GPNA) is widely used to inhibit the glutamine transporter ASCT2, although it is known that it also inhibits other sodium-dependent amino acid transporters. In a panel of human cancer cell lines, which express the system L transporters LAT1 and LAT2, GPNA inhibits the sodium-independent influx of leucine and glutamine.

Structural biology of ferritin nanocages
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Protein-Polyelectrolyte Complexes and Micellar Assemblies. [PDF]
In this review, we highlight the recent progress in our understanding of the structure, properties and applications of protein-polyelectrolyte complexes in both bulk and micellar assemblies. Protein-polyelectrolyte complexes form the basis of the genetic

Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Functional characterization of a glutamate/aspartate transporter from the mosquito Aedes aegypti [PDF]
Glutamate elicits a variety of effects in insects, including inhibitory and excitatory signals at both neuromuscular junctions and brain. Insect glutamatergic neurotransmission has been studied in great depth especially from the standpoint of the ...

Rate variation during molecular evolution: creationism and the cytochrome c molecular clock [PDF]
Molecular clocks based upon amino acid sequences in proteins have played a major role in the clarification of evolutionary phylogenies. Creationist criticisms of these methods sometimes rely upon data that might initially seem to be paradoxical.

Abstract Inhibition of uptake of cationic amino acids by certain neutral amino acids in the presence of alkali metal ions has been studied in the Ehrlich ascites tumor cell, in the rabbit reticulocyte and in yeast. When a hydroxyl group is introduced on carbon 4 (for the reticulocyte) or carbon 5 (for the Ehrlich cell) of straight chain amino acids, a ...

Tau acetylation at K331 has limited impact on tau pathology in vivo
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.
