Webb23 juli 2024 · Introduction. As an essential organelle, the lysosome is responsible for various cellular processes, including protein turnover and recycling, energy metabolism, intracellular signaling, and nutrient storage [1–3].The lysosome membrane contains hundreds of transmembrane proteins, many of which are transporters and channels that … WebbOnce within a cell, these surface proteins can be either destroyed or “recycled” back to the membrane. The cell surface biotinylation assay provides researchers with a way to study these phenomena. The technique makes use of a derivative of the small molecule biotin, which can label surface proteins and then be chemically cleaved.

WebbTurnover can be detected visually by microscopy techniques. Various protein labeling methods for pulse-chase have specific application potentials. Reporter fluorescence fusion proteins are often used, but they can disrupt the native target protein's complexing behavior, be toxic to the cells, or affect target stability for pulse chase experiments. Protein groups were inferred from a high-quality subset of the peptide identifications made by Mascot. All of the peptides must pass the 1% (peptide) false discovery rates (FDR) criterion.
