Cryo–light microscopy with angstrom precision deciphers structural conformations of PIEZO1 in its native state

Hisham Mazal, Franz-Ferdinand Wieser, Daniel Bollschweiler, Alexandra Schambony et autres

Investigations based on cryo-electron microscopy (cryo-EM), atomic force microscopy, and super-resolution microscopy reveal a symmetric trimer with propeller-like blades for the mechanosensitive ion channel PIEZO. However, a conclusive understanding of its conformations in the cell membrane is lacking. Here, we implement a …

NCBP2-AS2 is a mitochondrial microprotein, regulates energy metabolism and neurogenesis, and is downregulated in Alzheimer’s disease

Stanislava Dimitrova Popova, Prabesh Bhattarai, Elanur Yılmaz, Daniela Lascu et autres

Microproteins, short functional peptides encoded by small genes, are emerging as critical regulators of cellular processes, yet their roles in mitochondrial function and neurodegeneration remain underexplored. In this study, we identify NCBP2-AS2 as an evolutionarily conserved mitochondrial microprotein with significant roles in …

Cryogenic light microscopy with Ångstrom precision deciphers structural conformations of PIEZO1

Hisham Mazal, Alexandra Schambony, Vahid Sandoghdar

Abstract Despite the impressive progress in molecular biochemistry and biophysics, many questions regarding the conformational states of large (transmembrane) protein complexes persist. In the case of the PIEZO protein, investigations by cryogenic electron microscopy (Cryo-EM) and atomic force microscopy (AFM) have established …

Noncanonical WNT5A controls the activation of latent TGF-β to drive fibroblast activation and tissue fibrosis

Thuong Trinh‐Minh, Chih-Wei Chen, Cuong Tran Manh, Yinan Li et autres

Transforming growth factor β (TGF-β) signaling is a core pathway of fibrosis, but the molecular regulation of the activation of latent TGF-β remains incompletely understood. Here, we demonstrate a crucial role of WNT5A/JNK/ROCK signaling that rapidly coordinates the activation of latent TGF-β …

A paintbrush for delivery of nanoparticles and molecules to live cells with precise spatiotemporal control

Cornelia Holler, Richard W. Taylor, Alexandra Schambony, Leonhard Möckl et autres

Delivery of very small amounts of reagents to the near-field of cells with micrometer spatial precision and millisecond time resolution is currently out of reach. Here we present μkiss as a micropipette-based scheme for brushing a layer of small molecules and nanoparticles …

High-Precision Protein-Tracking With Interferometric Scattering Microscopy

Richard W. Taylor, Cornelia Holler, Reza Gholami Mahmoodabadi, Michelle Küppers et autres

The mobility of proteins and lipids within the cell, sculpted oftentimes by the organization of the membrane, reveals a great wealth of information on the function and interaction of these molecules as well as the membrane itself. Single particle tracking has proven …

Lipid Dynamics in Membranes Slowed Down by Transmembrane Proteins

Lisa Ebersberger, Torben Schindler, Sonja A. Kirsch, Kristýna Pluháčková et autres

Lipids and proteins, as essential components of biological cell membranes, exhibit a significant degree of freedom for different kinds of motions including lateral long-range mobility. Due to their interactions, they not only preserve the cellular membrane but also contribute to many important …

Molecular cross-talk between Y5-receptor and neuropeptide Y drives liver cancer

Peter N. Dietrich, Laura Wormser, Vanessa Fritz, Tatjana Seitz et autres

Background Hepatocellular carcinoma (HCC) is clearly age-related and represents one of the deadliest cancer types worldwide. Due to globally increasing risk factors including metabolic disorders, the incidence rates of HCC are still rising. However, the molecular hallmarks of HCC remain poorly understood. …
