Bioid biotinylation
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 … Webbiotinylation. The covalent linking of biotin to a protein, peptide, nucleic acid (DNA, RNA) or other biomolecule of interest, which in turn binds with high affinity to avidin or streptavidin …
