New Turf for CFP/YFP FRET Imaging of Membrane Signaling Molecules [PDF]
TIRF microscopy can be used in conjunction with CFP/YFP FRET to detect movements of the cytoplasmic tails of GIRK channels (Riven et al., this issue of Neuron). This innovative combination of techniques allows molecular resolution of small motions underlying ion channel activation by G proteins and will likely find widespread use for study of membrane ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

Targeting FRET-Based Reporters for cAMP and PKA Activity Using AKAP79
Fluorescence resonance energy transfer (FRET)-based sensors for 3′–5′cyclic adenosine monophosphate (cAMP) and protein kinase A (PKA) allow real-time imaging of cAMP levels and kinase activity in intact cells with high spatiotemporal ...

Interbase-FRET binding assay for pre-microRNAs [PDF]
The aberrant expression of microRNAs (miRs) has been linked to several human diseases. A promising approach for targeting these anomalies is the use of small-molecule inhibitors of miR biogenesis.

Chasing the signaling run by tri-molecular time-lapse FRET microscopy [PDF]
AbstractA feasible design is made to measure three protein/protein interactions to visualize signal pathways by time-lapse Förster resonance energy transfer (FRET) microscopy. When interacting proteins are in close proximity, excitation energy is provided to allow the energy flow from the first molecule to excite the second, followed by energy transfer

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Enhancement of Probe Signal for Screening of HIV-1 Protease Inhibitors in Living Cells
The global human immunodeficiency virus infection/acquired immuno-deficiency syndrome (HIV/AIDS) epidemic is one of the biggest threats to human life. Mutation of the virus and toxicity of the existing drugs necessitate the development of new drugs for ...
