Mitochondrial Impairment: A Common Motif in Neuropsychiatric Presentation? The Link to the Tryptophan–Kynurenine Metabolic System [PDF]

open access: yes, 2022
Nearly half a century has passed since the discovery of cytoplasmic inheritance of human chloramphenicol resistance. The inheritance was then revealed to take place maternally by mitochondrial DNA (mtDNA).

The Multiple Functions of Rho GTPases in Fission Yeasts [PDF]

open access: yes, 2021
The Rho family of GTPases represents highly conserved molecular switches involved in a plethora of physiological processes. Fission yeast Schizosaccharomyces pombe has become a fundamental model organism to study the functions of Rho GTPases over the ...

FRET sensors reveal the retinal entry pathway in the G protein-coupled receptor rhodopsin

open access: yesiScience, 2022
Summary: The photoreceptor rhodopsin (Rho) becomes active when a tethered inverse agonist ligand (11CR) is photoconverted to an agonist (ATR). The ligand-binding pocket of inactive rhodopsin is completely enclosed, whereas active rhodopsin displays pores

Biophysical Tools to Study Cellular Mechanotransduction [PDF]

open access: yesBioengineering, 2017
The cell membrane is the interface that volumetrically isolates cellular components from the cell’s environment. Proteins embedded within and on the membrane have varied biological functions: reception of external biochemical signals, as membrane channels, amplification and regulation of chemical signals through secondary messenger molecules ...

Synaptophysin 1 Clears Synaptobrevin 2 from the Presynaptic Active Zone to Prevent Short-Term Depression

open access: yesCell Reports, 2016
Release site clearance is an important process during synaptic vesicle (SV) recycling. However, little is known about its molecular mechanism. Here we identify self-assembly of exocytosed Synaptobrevin 2 (Syb2) and Synaptophysin 1 (Syp1) by homo- and ...

Cholesterol-induced suppression of Kir2 channels is mediated by decoupling at the inter-subunit interfaces

open access: yesiScience, 2022
Summary: Cholesterol is a major regulator of multiple types of ion channels. Although there is increasing information about cholesterol binding sites, the molecular mechanisms through which cholesterol binding alters channel function are virtually ...

MMP-9 Signaling Pathways That Engage Rho GTPases in Brain Plasticity [PDF]

open access: yes, 2021
The extracellular matrix (ECM) has been identified as a critical factor affecting synaptic function. It forms a functional scaffold that provides both the structural support and the reservoir of signaling molecules necessary for communication between ...

In vitro assembly, positioning and contraction of a division ring in minimal cells

open access: yesNature Communications, 2022
Constructing a minimal protein machinery for self-division of membrane compartments is a major goal of bottom-up synthetic biology. Here, authors achieved the assembly, placement and onset of contraction of a minimal division ring in lipid vesicles.
