Proximity labeling users: check out this study by @zhixingchen2.bsky.social and Peng Zou, which establishes how much contact-dependence vs. diffusion is responsible for biotinylation — tl;dr TurboID has a much smaller effective radius! www.nature.com/articles/s41... 1/2

New paper from @zhixingchen2.bsky.social's lab! It turns out that, in addition to its very low phototoxicity, PKmito Deep Red (PKMDR) directly reports on mitochondrial membrane potential (MMP) in live cells through its lifetime! www.nature.com/articles/s41...

How and when to measure mitochondrial inner membrane potentials
The scientific literature on mitochondria has increased significantly over the years due to findings that these organelles have widespread roles in the onset and progression of pathological conditions such as metabolic disorders, neurodegenerative and cardiovascular diseases, inflammation, and cancer. Researchers have extensively explored how mitochondrial properties and functions are modified in different models, often using fluorescent inner mitochondrial membrane potential (ΔΨm) probes to assess functional mitochondrial aspects such as protonmotive force and oxidative phosphorylation.

How proximal is proximity labeling❓ Using DNA nanorulers we found that TurboID/BioID are largely contact labeling, while APEX2 also bears a major contact labeling pathway in parallel with diffusive labeling. www.biorxiv.org/content/10.1... Special thanks to @aliceyting.bsky.social for discussions
