Membrane trafficking involves transport of proteins from the plasma membrane to the cell interior (i.e. endocytosis) followed by trafficking to lysosomes for degradation or to the plasma membrane for recycling. Methods described in this article are designed to study endocytosis and recycling of plasma membrane proteins.
Overview
This article discusses membrane trafficking, focusing on the transport of proteins from the plasma membrane into the cell interior through endocytosis. It outlines methods to study the recycling of plasma membrane proteins and their degradation in lysosomes.
