Advances in GPCRs Associated With Wnt Signaling Within the Auditory System

open access: yesMedicine Bulletin, EarlyView.
ABSTRACT G protein‐coupled receptors (GPCRs) that interact with the Wnt signaling pathway are pivotal for auditory system homeostasis, as they orchestrate inner ear development, hair cell (HC) regeneration, and hearing preservation. Frizzled (FZD) receptors, the core Wnt‐related GPCRs, bind Wnt ligands and co‐receptors (e.g., LRP5/6) to activate both ...

Atomic structures and deletion mutant reveal different capsid-binding patterns and functional significance of tegument protein pp150 in murine and human cytomegaloviruses with implications for therapeutic development. [PDF]

open access: yes, 2019
Cytomegalovirus (CMV) infection causes birth defects and life-threatening complications in immunosuppressed patients. Lack of vaccine and need for more effective drugs have driven widespread ongoing therapeutic development efforts against human CMV (HCMV)

Rational acquisition of laboratory equipment: an accurate mathematical model to estimate the trade‐offs in shared and nonshared equipment

open access: yesActa Crystallographica Section D, EarlyView.
We present a quantitative framework combining cost modelling and queueing theory to estimate hourly access costs, waiting times and congestion levels for shared high‐end scientific equipment. The approach is general, illustrated with cryo‐electron microscopy examples, and implemented in an open‐access online calculator to support evidence‐based ...

Some Like It Hot –Structural Changes in Extremophile Rubredoxin at 120 °C

open access: yesAngewandte Chemie, Volume 138, Issue 5, 28 January 2026.
We reveal the high temperature crystal structure of a hyperthermophilic (Pyrococcus furiosus) rubredoxin at 393 K (120 °C), together with multiple complementary structures down to 100 K. The results are compared with molecular dynamics calculations. Significant changes in H‐bonding are observed.

Analytic modeling of inhomogeneous-resolution maps in cryo-electron microscopy and crystallography

open access: yesIUCrJ, 2022
Refinement of macromolecular atomic models versus experimental maps in crystallography and cryo-electron microscopy is a critical step in structure solution.

Recent advances in our understanding of the structure and function of more unusual cation channels. [PDF]

open access: yes, 2019
As their name implies, cation channels allow the regulated flow of cations such as sodium, potassium, calcium, and magnesium across cellular and intracellular membranes.

Liquid-crystalline phase transitions in lipid droplets are related to cellular states and specific organelle association.

open access: yes, 2019
Lipid droplets (LDs) are ubiquitous organelles comprising a central hub for cellular lipid metabolism and trafficking. This role is tightly associated with their interactions with several cellular organelles.

Tropomyosin Positions in Regulated Thin Filaments Revealed by Cryoelectron Microscopy [PDF]

open access: yesBiophysical Journal, 1999
Past attempts to detect tropomyosin in electron micrograph images of frozen-hydrated troponin-regulated thin filaments under relaxing conditions have not been successful. This raised the possibility that tropomyosin may be disordered on filaments in the off-state, a possibility at odds with the steric blocking model of muscle regulation.

Damage‐limited resolution for X‐ray and electron microscopy of organic specimens

open access: yesActa Crystallographica Section D, Volume 82, Issue 5, Page 471-483, May 2026.
Analytical expressions for the damage‐limited resolution are developed and applied to X‐ray and electron imaging of beam‐sensitive specimens. The findings will guide future microscopy and instrument design.Analytical expressions for the damage‐limited resolution (DLR) are developed and applied to X‐ray and electron imaging of beam‐sensitive specimens ...

Postsynaptic protein organization revealed by electron microscopy. [PDF]

open access: yes, 2019
Neuronal synapses are key devices for transmitting and processing information in the nervous system. Synaptic plasticity, generally regarded as the cellular basis of learning and memory, involves changes of subcellular structures that take place at the ...
