Are we there yet? Initial targeting of the Male-Specific Lethal and Polycomb group chromatin complexes in Drosophila [PDF]

Open Biology, 2014
Chromatin-binding proteins must navigate the complex nuclear milieu to find their sites of action, and a constellation of protein factors and other properties are likely to influence targeting specificity. Despite considerable progress, the precise rules

The Mechanism of NLRP3 Inflammasome Activation and Its Roles in Chronic Rhinosinusitis

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT NLRP3 (NLR family pyrin domain containing 3) is one of the crucial receptors in pathogen recognition receptor (PRR) families which can recognize the pathogen‐associated molecular patterns (PAMPs) and the damage‐associated molecular patterns (DAMPs), thus triggering innate immune response. After NLRP3 activation, it recruits the adaptor protein

Assembly and functional analysis of an S/MAR based episome with the cystic fibrosis transmembrane conductance regulator gene [PDF]

, 2018
Improving the efficacy of gene therapy vectors is still an important goal toward the development of safe and efficient gene therapy treatments. S/MAR (scaffold/matrix attached region)-based vectors are maintained extra-chromosomally in numerous cell ...

Increased expression of inflammasome signaling genes and proteins in selective brain regions in the intermediate stage of Alzheimer's disease

Brain Pathology, EarlyView.
Neuritic plaques increase in the intermediate stage of Alzheimer's neuropathological change. The intermediate stage of Alzheimer's disease was investigated by transcriptomics and immunohistochemistry. This revealed that inflammasome sensors NLRP1, NLRP3, and AIM2 oligomerize with ASC speck to form the inflammasome complex and initiate the downstream ...

Molecular architecture of meiotic multiprotein complexes

, 2020
Sich sexuell fortpflanzende Organismen sind auf die Meiose angewiesen, um haploide, genetisch vielfältige Keimzellen zu erzeugen, die die Stabilität des Genoms und die Fähigkeit zur Anpassung an sich verändernde Umgebungen erhalten. Die Haploidisierung wird durch zwei aufeinanderfolgende Runden der Zellteilung nach einer einzigen anfänglichen prä ...

Compartmentalisation in cAMP signalling: A phase separation perspective

British Journal of Pharmacology, EarlyView.
Cells rely on precise spatiotemporal control of signalling pathways to ensure functional specificity. The compartmentalisation of cyclic AMP (cAMP) and protein kinase A (PKA) signalling enables distinct cellular responses within a crowded cytoplasmic space.

Structure-function mapping of a heptameric module in the nuclear pore complex. [PDF]

, 2012
The nuclear pore complex (NPC) is a multiprotein assembly that serves as the sole mediator of nucleocytoplasmic exchange in eukaryotic cells. In this paper, we use an integrative approach to determine the structure of an essential component of the yeast ...

Targeting the noncatalytic activity of GSK3β modulates neuronal excitability in medium spiny neurons via Nav1.6 interactions

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Kinases phosphorylate ion channels, but their noncatalytic roles via protein–protein interactions (PPI) are less understood. Here, we identified the peptidomimetic ZL141 to characterize the PPI between GSK3β and Nav1.6, revealing a noncatalytic role for GSK3β in regulating Nav1.6 currents and neuronal excitability ...

Phosphorylation-mediated interactions with TOPBP1 couple 53BP1 and 9-1-1 to control the G1 DNA damage checkpoint

eLife, 2019
Coordination of the cellular response to DNA damage is organised by multi-domain ‘scaffold’ proteins, including 53BP1 and TOPBP1, which recognise post-translational modifications such as phosphorylation, methylation and ubiquitylation on other proteins ...
