Biotinylated Cell-Penetrating Peptide Probe to Detect Protein-Protein Interactions
0 Views •
2025
This video demonstrates a technique that uses biotinylated cell-penetrating peptides to detect intracellular protein-protein interactions. The cell-penetrating peptides facilitate the conjugated peptide to enter a cell and specifically bind to its interacting proteins. The biotin, after binding to avidin, allows purification of the interacting proteins’ complex from a cell lysate.

Here, we describe the application of three-dimensional fluorescence recovery after photobleaching (3D-FRAP) for the analysis of the gap junction-dependent shuttling of miRNA. In contrast to commonly applied methods, 3D-FRAP allows for the quantification of the intercellular transfer of small RNAs in real time, with high spatio-temporal resolution.

The goal of this experiment is to determine and control the size, shape and stability of self-assembled discotic amphiphiles in water. For aqueous based supramolecular polymers such level of control is very difficult. We apply a strategy using both repulsive and attractive interactions. The experimental techniques applied to characterize this system are broadly applicable.

Improved Polydimethylsiloxane (PDMS) Double Casting via Silicone Oil Treatment for Densely Packed Microstructure Replication
0 Views •
2025
This protocol presents an improved demolding procedure for the Polydimethylsiloxane (PDMS) double casting technique by introducing silicone oil as a non-adhesive barrier between PDMS layers. Unlike plasma or chemical surface modification methods, this approach requires no specialized or costly equipment, making it a more accessible and cost-effective alternative.
FAQs
Ser279 and Ser282 provide potential phosphorylation sites within the peptide. Protein kinases can recognize these serine residues and transfer phosphate from ATP to them. This modification introduces additional negative charge, which can alter the peptide’s chemical properties and its potential interactions with other proteins. Comparing phosphorylated and unmodified forms helps investigators examine consequences of kinase activity.
ATP supplies the phosphate group transferred by the kinase to a serine residue in Connexin43 266-283. The reaction therefore links kinase activity to a measurable chemical change in the peptide. Because phosphorylation changes charge and may influence protein interactions, ATP-dependent modification provides a biochemical connection between signaling reactions and possible regulation of connexin43.
Phosphorylation changes the peptide’s charge and can modify how it interacts with proteins. Those altered interactions may help explain how signaling regulates connexin43 beyond the peptide sequence itself. Studying the modified segment therefore provides a focused way to connect a specific post-translational modification with broader effects on gap-junction assembly, channel activity, and intercellular communication.
Its defined sequence contains serine residues, including Ser279 and Ser282, that can serve as kinase-recognition and phosphorylation sites. Using this short, specified substrate reduces the complexity of studying kinase action on the larger connexin43 protein. Results can then clarify whether phosphorylation occurs at this regulatory region and support analysis of signaling pathways affecting connexin43.
The peptide is provided as a defined substrate in an ATP-dependent kinase reaction. Investigators examine phosphorylation of its serine-containing sequence to study kinase activity and the resulting modification. This focused assay can be used in phosphorylation studies and pathway analysis, offering a controlled biochemical system before relating the findings to connexin43 regulation and cellular communication.
Phosphorylation studies using Connexin43 266-283 can help connect kinase signaling with changes in connexin43 regulation. The resulting information may clarify how modification of the cytoplasmic C-terminal region relates to gap-junction assembly, channel activity, and intercellular communication. In biochemistry, the peptide therefore links a defined molecular event to broader cellular outcomes.
