Fluorescent Assay for Estimating the Binding of Erythromycin Derivatives to Ribosomes [PDF]

Antimicrobial Agents and Chemotherapy, 1978
A fluorescent erythromycin derivative was used to determine the binding of erythromycin derivatives to ribosomes. The assay is rapid, sensitive, and convenient. Because measurements are made in solution, they represent equilibrium conditions, unlike filter binding assays which perturb the equilibrium.

Inhibiting stearoyl‐CoA desaturase suppresses bone metastatic prostate cancer by modulating cellular stress, mTOR signaling, and DNA damage response

FEBS Letters, EarlyView.
Bone metastasis in prostate cancer (PCa) patients is a clinical hurdle due to the poor understanding of the supportive bone microenvironment. Here, we identify stearoyl‐CoA desaturase (SCD) as a tumor‐promoting enzyme and potential therapeutic target in bone metastatic PCa.

Clostridium perfringensepsilon toxin H149A mutant as a platform for receptor binding studies [PDF]

, 2013
Clostridium perfringens epsilon toxin (Etx) is a pore-forming toxin responsible for a severe and rapidly fatal enterotoxemia of ruminants. The toxin is classified as a category B bioterrorism agent by the U.S.

Fluorescence Recovery Assay for the Detection of Protein−DNA Binding

Analytical Chemistry, 2008
We report a novel and straightforward fluorescence recovery assay which enables the detection of protein-DNA interactions and simultaneously determines relative binding affinities of sequence-specific DNA-binding proteins for a variety of DNA sequences in a multiplexed format.

Development of a Microplate-Based, Electrophoretic Fluorescent Protein Kinase A Assay: Comparison with Filter-Binding and Fluorescence Polarization Assay Formats [PDF]

SLAS Discovery, 2005
A microplate-based electrophoretic assay has been developed for the serine/threonine kinase protein kinase A (PKA). The ElectroCapture PKA assay developed uses a positively charged, lissamine-rhodamine-labeled kemptide peptide substrate for the kinase reaction and Nanogen's ElectroCapture HTS Workstation and 384-well laminated membrane plates to ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Conformational Dynamics of the Plug Domain of the SecYEG Protein-conducting Channel [PDF]

, 2011
The central pore of the SecYEG preprotein-conducting channel is closed at the periplasmic face of the membrane by a plug domain. To study its conformational dynamics, the plug was labeled site-specifically with an environment-sensitive fluorophore.

A HABA dye-based colorimetric assay to detect unoccupied biotin binding sites in an avidin-containing fusion protein

BioTechniques
Avidin-biotin binding, the most robust non-covalent protein-ligand interaction occurring in nature, has wide-ranging applications in biotechnology. A frequent challenge in these applications is accurately determining the number of unoccupied biotin ...

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Identification of the catalytic motif of the microbial ribosome inactivating cytotoxin colicin E3 [PDF]

, 2004
Colicin E3 is a cytotoxic ribonuclease that specifically cleaves 16S rRNA at the ribosomal A-site to abolish protein synthesis in sensitive Escherichia coli cells.
