Ionic selectivity and thermal adaptations within the voltage-gated sodium channel family of alkaliphilic Bacillus [PDF]

open access: yes, 2014
Entry and extrusion of cations are essential processes in living cells. In alkaliphilic prokaryotes, high external pH activates voltage-gated sodium channels (Nav), which allows Na+ to enter and be used as substrate for cation/proton antiporters ...

Disordered N‐termini enhance the thermostability of SGNH‐hydrolase family polyesterases

open access: yesProtein Science, Volume 35, Issue 1, January 2026.
Abstract Polyesters are widely used plastics that persist in the environment due to their resistance to degradation. Microbial polyesterases potentially offer recycling and remediation solutions. However, most polyesterases lack the thermostability and catalytic efficiency required for practical application.

Structural Characterization of the Extracellular Domain of CASPR2 and Insights into Its Association with the Novel Ligand Contactin1 [PDF]

open access: yes, 2015
Contactin-associated protein-like 2 (CNTNAP2) encodes for CASPR2, a multidomain single transmembrane protein belonging to the neurexin superfamily that has been implicated in a broad range of human phenotypes including autism and language impairment.

Infrared Neural Stimulation Elicits Distinct Molecular Pathways in Astrocytes Based on Laser Pulse Parameters

open access: yesAdvanced Biology, Volume 9, Issue 12, December 2025.
Infrared (IR) light evokes distinct calcium and water transport responses in astrocytes, depending on stimulation duration and protocol. This study uses widefield imaging and pharmacology to reveal differential engagement of astroglial signaling pathways.

Molecular pathophysiology and pharmacology of the voltage-sensing module of neuronal ion channels [PDF]

open access: yes, 2015
Voltage-gated ion channels (VGICs) are membrane proteins that switch from a closed to open state in response to changes in membrane potential, thus enabling ion fluxes across the cell membranes.

Pigment Epithelium‐Derived Factor Deficiency Impairs Hippocampal Glutamate Homeostasis and Cognitive Function by Downregulating Astrocytic GLT‐1

open access: yesAdvanced Science, Volume 12, Issue 45, December 4, 2025.
The chronic glutamate‐induced excitotoxicity hypothesis has profoundly informed the therapeutic strategies employed in Alzheimer’s disease (AD). This study shows pigment epithelium‐derived factor (PEDF) regulates astrocytic glutamate transporter‐1 (GLT‐1)‐mediated glutamate homeostasis and cognition. Reduced PEDF correlates with lower Mini‐Mental State

Altered chemomechanical coupling causes impaired motility of the kinesin-4 motors KIF27 and KIF7. [PDF]

open access: yes, 2018
Kinesin-4 motors play important roles in cell division, microtubule organization, and signaling. Understanding how motors perform their functions requires an understanding of their mechanochemical and motility properties.

Microglia Display Altered Spatial Morphology and Proteome After Stroke

open access: yesPROTEOMICS, Volume 25, Issue 23, Page 59-76, December 2025.
ABSTRACT Microglia are abundantly distributed throughout the central nervous system (CNS) to play critical roles in neural development and homeostasis, and act as immune sentinels to constantly monitor their surrounding neural environment. Given their high reactivity to brain insults, we hypothesised that the cerebral microenvironment altered by ...

Membrane binding of a cyanobacterial ESCRT‐III protein crucially involves the helix α1‐3 hairpin conserved in all superfamily members

open access: yesProtein Science, Volume 34, Issue 12, December 2025.
Abstract IM30, the inner membrane‐associated protein of 30 kDa (also known as Vipp1) is essential for thylakoid membrane biogenesis and/or maintenance in chloroplasts and cyanobacteria. IM30 and its bacterial homolog PspA belong to the ESCRT‐III superfamily, proteins previously thought to be restricted to eukaryotes and archaea.

The Caenorhabditis elegans Iodotyrosine Deiodinase Ortholog SUP-18 Functions through a Conserved Channel SC-Box to Regulate the Muscle Two-Pore Domain Potassium Channel SUP-9 [PDF]

open access: yes, 2013
Loss-of-function mutations in the Caenorhabditis elegans gene sup-18 suppress the defects in muscle contraction conferred by a gain-of-function mutation in SUP-10, a presumptive regulatory subunit of the SUP-9 two-pore domain K+ channel associated with ...
