Tracking Internalized Membrane Proteins

Description

Cell-surface biotinylation assay is a method for tracking membrane proteins that move inside a cell through endocytosis. Endocytosis is the process cells use to take proteins from the membrane into the cytoplasm. Once inside, those proteins may be broken down or returned to the membrane by recycling.

Transcript

Labeling of cell surface proteins with biotin presents a powerful tool to study cellular transport pathways involved in regulating membrane proteins. A cell maintains a tightly regulated set of proteins at the surface, so that it can receive and respond to extracellular information via several signaling pathways. Endocytosis, ...
