We optimized the protocol of biotin labeling and affinity purification in transgenic Arabidopsis expressing a BIN2-TurboID fusion protein. Subsequent quantitative mass spectrometry (MS) analysis identified about three hundred proteins biotinylated by BIN2-TurboID more efficiently than the YFP-TurboID control. And yet, exactly what’s contained in these frequent precursors to black holes remains an open question. and A.Y.T. Here, we used proximity labeling (PL) to identify the proteome proximal to N, which is an NLR that confers resistance to Tobacco mosaic virus (TMV). Epub 2016 Jul 27.

Overall, split-TurboID is a versatile tool for conditional and spatially specific proximity labeling in cells. Cells. Enter multiple addresses on separate lines or separate them with commas. Online ISSN 1091-6490. However, current PL methods … Efficient proximity labeling in living cells and organisms with TurboID Print 2020 Oct 27. and T.C.B. Our study illustrates that PL-MS using TurboID is a powerful tool for mapping signaling networks, and reveals broad roles of BIN2 kinase in cellular signaling and regulation in plants. Here’s a way forward—a more stringent and comprehensive strategy. To improve the specificity and versatility of PL, we developed split-TurboID, a promiscuous biotinylating enzyme split into two inactive fragments. | Here we demonstrate the application of enzyme-catalyzed proximity labeling (PL), using the engineered promiscuous biotin ligase TurboID, as a sensitive method for characterizing PPIs in signaling networks. and A.Y.T.
