Webbför 2 dagar sedan · Proximity labeling (PL) coupled with mass spectrometry has emerged as a powerful technique to map proximal protein interactions in living cells. Large-scale sample processing for proximity proteomics necessitates a high-throughput workflow to reduce hands-on time and increase quantitative reproducibility. To address this issue, we … Webb11 jan. 2024 · Proximity labeling (PL) is a technology for tagging the endogenous interaction partners of specific protein ‘baits’, via genetic fusion to promiscuous enzymes that catalyze the generation of...
In Vivo Proximity Labeling for the Detection of Protein–Protein …
WebbWe describe the development of a proximity-induced bio-orthogonal inverse electron demand Diels–Alder reaction that exploits the high-affinity interaction between a dienophile-modified RhoBAST aptamer and its tetramethyl rhodamine methyltetrazine substrate. We applied this concept for covalent RNA labeling in proof-of-principle … Webb8 sep. 2024 · We anticipate a growing repertoire of RNA-centered proximity labeling tools to further expand our analysis of cellular RNAs. An important limitation of our approach and other RNA proximity labeling studies (12, 13) is that they have only been demonstrated on overexpressed, and/or highly abundant cellular RNAs. habeck in bayreuth
