Regulation of Catch Binding by Allosteric Transitions [PDF]

The Journal of Physical Chemistry B, 2010
An allosteric model is used to describe changes in lifetimes of biological receptor-ligand bonds subjected to an external force. Force-induced transitions between the two states of the allosteric site lead to changes in the receptor conformation. The ligand bound to the receptor fluctuates between two different potentials formed by the two receptor ...

Ultrasensitive Detection of FKBP12 Using a Synthetic Receptor‐Functionalized QCM Nanoplatform

Advanced Sensor Research, EarlyView.
A reusable nanosensor platform for ultralow FKBP12 detection in physiological fluids is presented. Combining a gold‐coated QCM with a custom‐designed receptor in a self‐assembled monolayer, the device achieves picomolar sensitivity and high selectivity.

Loss of NR2F6 Protects from Salmonella Typhimurium Infection

Advanced Science, EarlyView.
Loss of nuclear receptor NR2F6 reduces tissue‐resident macrophage populations. Nr2f6‐deficient mice are protected from weight loss and bacterial load during infection with Salmonella Typhimurium. Pro‐inflammatory cytokines and iron levels are altered in infected Nr2f6‐deficient mice.

Disruption of ARID1B Recruitment to the Nuclear Pore Complex as a New Anticancer Therapeutic Strategy

Advanced Science, EarlyView.
This study identifies ARID1B as a chromatin‐bound driver of tumor growth in TNBC. ARID1B impairs ARID1A function and directly activates oncogenic programs through SWI/SNF remodeling. Its nuclear localization, mediated by the KPNA2–KPNB1–RANBP2 import machinery, is essential for its tumor‐promoting activity.

Allosteric Regulation by Components of a Critical Membrane [PDF]

Biophysical Journal, 2014
We present a simple model of a membrane bound protein allosterically regulated by the local lipid composition. We are motivated by the experimental finding that the plasma membranes of mammalian cells are tuned close to a liquid-liquid critical point, where the sensitivity of many properties to perturbations is large.

Allosteric Regulation of E-Cadherin Adhesion [PDF]

Journal of Biological Chemistry, 2015
Cadherins are transmembrane adhesion proteins that maintain intercellular cohesion in all tissues, and their rapid regulation is essential for organized tissue remodeling. Despite some evidence that cadherin adhesion might be allosterically regulated, testing of this has been hindered by the difficulty of quantifying altered E-cadherin binding affinity

RPL6 Interacts with HMGCS1 to Stabilize HIF‐1α by Promoting Cholesterol Production in Hepatocellular Carcinoma

Advanced Science, EarlyView.
The study found that RPL6 is frequently upregulated in HCC tissues with extrahepatic metastasis. Elevated RPL6 bound to and increased the stability of HMGCS1 mRNA, thereby enhancing intracellular cholesterol levels. Subsequently, increased cholesterol promotes cancer metastasis in HCC by stabilizing HIF‐1α protein.

Developmental Hypoxia Enhances Kidney Organoid Complexity and Maturity

Advanced Science, EarlyView.
The current bottleneck in metanephric mesenchyme (MM)‐derived nephron organoid development is the absence of a connected network of collecting ducts (CD) derived from the ureteric bud (UB). To address this limitation, this study proposes a hypoxia‐based differentiation method that mimics the natural renal developmental environment, enabling the ...

A Prion‐Like Domain in EBV EBNA1 Promotes Phase Separation and Enables SRRM1 Splicing

Advanced Science, EarlyView.
This study discoveries that EBV EBNA1 behaves as a prion‐like protein, verified using cell‐based assays and the Saccharomyces cerevisiae Sup35p prion identification system. The prion‐like domain of EBNA1 drives liquid–liquid phase separation. EBNA1 interacts with the splicing factor SRSF1 to regulate the expression of the SRRM1 splicing isoforms ...

Activation of Kir4.1 Channels by 2‐D08 Promotes Myelin Repair in Multiple Sclerosis

Advanced Science, EarlyView.
Multiple sclerosis causes myelin loss and neurological dysfunction. This study shows that 2‐D08, a small molecule targeting Kir4.1 channels, promotes OPCs differentiation via FYN tyrosine kinase phosphorylation and the FYN/MYRF pathway. It significantly improves myelin repair and motor deficits in EAE mice and marmosets, highlighting its potential as a
