WebDec 29, 2016 · BioID was developed as a tool to biotinylate proteins that (transiently) associate with or are spatially close to a protein-of-interest (POI) in intact cells [ 3 - 5]. It involves the expression of a mutant of the bacterial biotin ligase BirA fused to a POI. WebOct 7, 2024 · Here we report an extensive BioID-based proximity map of a human cell, comprising 192 markers from 32 different compartments that identifies 35,902 unique high confidence proximity interactions and localizes 4,145 proteins expressed in HEK293 cells. The recall of our localization predictions is on par with or better than previous large-scale ...
Biotin Proximity Labeling for Protein–Protein Interaction
WebIn recent years, proximity-dependent biotinylation approaches, including BioID, APEX, and their derivatives, have been widely used to define the compositions of organelles and other structures in cultured cells and model organisms. The associations between specific proteins and given compartments are regulated by several post-translational modifications … WebQuantitative and qualitative analyses of cell protein composition using liquid chromatography/tandem mass spectrometry are now standard techniques in biological and clinical research. However, the quantitative analysis of protein–protein interactions (PPIs) in cells is also important since these interactions are the bases of many … gerbes application online
