Purification, Fluorescent Labeling, and Detyrosination of Mammalian Cell Tubulin for Biochemical Assays

Cytoskeleton, EarlyView.
ABSTRACT Microtubules play essential roles in numerous cellular processes. All microtubules are built from the protein tubulin, yet individual microtubules can differ spatially and temporally due to their tubulin isotype composition and post‐translational modifications (PTMs).

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1

Cytoskeleton, EarlyView.
ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...

Expression, Purification, and Microscopy‐Based Assays for Engineered Recombinant Tyrosinated, Detyrosinated, and Δ2 Human Tubulin

Cytoskeleton, EarlyView.
ABSTRACT Microtubules are noncovalent polymers assembled from α/β tubulin dimers. Their structure, dynamics and interaction with effectors are regulated through the expression of diverse tubulin isotypes and chemically diverse posttranslational modifications, also known as the “tubulin code.” Understanding the biophysical correlates between tubulin ...

TIRF Imaging of Lipid Bilayer Arrays

Biophysical Journal, 2011
A TIRF imaging platform for the simultaneous interrogation of multiple lipid bilayers in an arrayed format has been developed. Here, a proof of principle demonstration is made with the quantification of Calcium flux through the trans membrane pore, alpha-hemolysin. The effect of pore blocking by cyclodextrins is also demonstrated.Utilising a droplet on

3D super-resolved multi-angle TIRF via polarization modulation

, 2018
Measuring the three dimension nanoscale organization of protein or cellular structures is challenging, especially when the structure is dynamic. Owing to the informative total internal reflection fluorescence (TIRF) imaging under varied illumination ...

Improving 3D MA-TIRF Reconstruction with Deconvolution and Background Estimation [PDF]

, 2019
International audienceTotal internal reflection fluorescence microscopy (TIRF) produces 2D images of the fluorescent activity integrated over a very thin layer adjacent to the glass coverslip. By varying the illumination angle (multi-angle TIRF), a stack

Engineering and Characterization of a Fluorescent Fission Yeast Arp2/3 Complex for Single Molecule Mechanistic Investigations

Cytoskeleton, EarlyView.
ABSTRACT Arp2/3 complex is a seven‐component protein complex that facilitates the assembly of branched actin filament networks by binding to pre‐existing “mother” actin filaments and initiating the nucleation of new branched “daughter” filaments. Arp2/3 complex must be activated by a nucleation promoting factor such as the WASP/Scar protein family. The

Automated single-molecule imaging in living cells

Nature Communications, 2018
Large scale live cell screens often lack single-molecule resolution. Here the authors present an artificial intelligence-assisted TIRF microscope with automated cell searching and focusing, and use it for high-throughput single-molecule imaging of EGFR ...

Mechanistic insights into HipA‐mediated bacterial persistence: Role of initial cellular states and toxin expression kinetics

mLife, EarlyView.
Abstract Persistent bacteria subpopulations showing multidrug tolerance pose significant challenges to antibiotic therapy. While the HipBA toxin–antitoxin (TA) system is known to play a role in persister formation, existing studies predominantly focus on its kinase activity and intracellular regulatory pathways, with limited attention to the ...

Supramolecular Polymer‐Surfactant Co‐Assemblies for Multivalent HSV‐1 Inhibition

Angewandte Chemie, Volume 138, Issue 39, 21 September 2026.
Non‐covalent co‐assembly of BTA with antiviral surfactants produces ratio‐dependent morphologies. Fibrous supramolecular polymers exhibit superior HSV‐1 inhibition, revealing multivalent fiber‐virus interactions and highlighting supramolecular co‐assemblies as a powerful strategy for functional biomedical nanomaterials with demonstrated tunable ...
