Noncanonical usage of stop codons in ciliates expands proteins with structurally flexible Q-rich motifs

open access: yeseLife
Serine(S)/threonine(T)-glutamine(Q) cluster domains (SCDs), polyglutamine (polyQ) tracts and polyglutamine/asparagine (polyQ/N) tracts are Q-rich motifs found in many proteins.

Current Challenges of Transcription Compartmentalization Research

open access: yesAdvanced Science, Volume 13, Issue 46, 17 August 2026.
Transcription factors, coactivators, and RNA polymerase II assemble into transcription compartments ranging from small, defined complexes to liquid‐like condensates. This review unifies these seemingly competing descriptions along a single continuum and asks what these compartments have been shown to do, and what they have not, revealing that the most ...

Mitochondrial membrane remodeling in stress adaptation: Lipid control of organelle quality

open access: yesProtein Science, Volume 35, Issue 8, August 2026.
Abstract Mitochondria respond to proteotoxic stress through the mitochondrial unfolded protein response, traditionally viewed as a transcriptional program that restores proteostasis by inducing chaperones and proteases. Emerging evidence indicates that mitochondrial membrane remodeling constitutes an additional adaptive component of this response ...

Advances in the nanostructure characterization of biological hydrogels formed by the prion‐like domain of EARLY FLOWERING 3

open access: yesActa Crystallographica Section D, Volume 82, Issue 8, Page 940-946, August 2026.
In biological systems, hydrogels often arise through liquid–liquid phase separation, where biomolecular condensates can age into gel‐like states. SAXS is a key technique to probe the molecular organization of these samples. This study introduces an in‐vacuum Gel‐Cell for SAXS‐based structural analysis of a biologically derived hydrogel formed by the ...

Lysine l‐Lactylation: Bridging Metabolism, Chromatin and Disease

open access: yesCell Proliferation, Volume 59, Issue 8, August 2026.
Enzymatic regulation of KL‐la. The enzymatic regulation of KL‐la involves two distinct pathways for L‐lactate accumulation: intracellular production through glycolysis‐derived pyruvate conversion by lactate dehydrogenase (LDH) or direct cellular uptake via monocarboxylate transporters (MCTs). These L‐lactate pools fuel two distinct lactylation pathways—

Remote Assessment of Ataxia Severity in SCA3 Across Multiple Centers and Time Points

open access: yesAnnals of Clinical and Translational Neurology, Volume 13, Issue 7, Page 1370-1378, July 2026.
ABSTRACT Objective Spinocerebellar ataxia type 3 (SCA3) is a genetically defined ataxia. The Scale for Assessment and Rating of Ataxia (SARA) is a clinician‐reported outcome that measures ataxia severity at a single time point. In its standard application, SARA fails to capture short‐term fluctuations, limiting its sensitivity in trials.

Polyglutamine Repeat Length-Dependent Proteolysis of Huntingtin

open access: yesNeurobiology of Disease, 2002
Amino-terminal fragments of huntingtin, which contain the expanded polyglutamine repeat, have been proposed to contribute to the pathology of Huntington's disease (HD).

Value of MRI Outcomes for Preventive and Early‐Stage Trials in Spinocerebellar Ataxias 1 and 3

open access: yesAnnals of Clinical and Translational Neurology, Volume 13, Issue 7, Page 1452-1466, July 2026.
ABSTRACT Objective To examine the value of MRI outcomes as endpoints for preventive and early‐stage trials of two polyglutamine spinocerebellar ataxias (SCAs). Methods A cohort of 100 participants (23 SCA1, 63 SCA3, median Scale for the Assessment and Rating of Ataxia (SARA) score = 5, 42% preataxic, and 14 gene‐negative controls) was scanned at 3T up ...

QBP1 Peptide as a Potential Anti‐Amyloidogenic Therapy for Type 2 Diabetes: An In Vitro Study

open access: yesAdvanced Science, Volume 13, Issue 37, 3 July 2026.
The anti‐amyloidogenic peptide QBP1 effectively halts human islet amyloid polypeptide (hIAPP) aggregation, preventing the formation of toxic β‐structured intermediates. Through a combination of biophysical assays, molecular dynamics, and cell‐based studies, QBP1 is shown to preserve β‐cell viability and metabolic homeostasis, positioning it as a ...
