Understanding living clathrin-coated pits.
Most knowledge of clathrin-mediated endocytosis has been gained by biochemical fractionation and in vitro assays. Recently, the study of endocytosis has extended into the living cell. The tracking of individual clathrin-coated pits and vesicles (CCPs and CCVs) has provided new insight into understanding the dynamic nature of CCPs. The use of total internal reflection fluorescence microscopy (TI...
متن کاملGM1-Containing Lipid Rafts Are Depleted within Clathrin-Coated Pits
Recent studies show that markers for lipid rafts are among the plasma membrane components most likely to be internalized independently of clathrin-coated pits, and there is evidence to suggest that lipid rafts may play a functional role in endocytic trafficking [1-5]. However, lipid rafts themselves are commonly defined purely in biochemical terms, by resistance to detergent extraction. The exi...
متن کاملDistinct Dynamics of Endocytic Clathrin-Coated Pits and Coated Plaques
Clathrin is the scaffold of a conserved molecular machinery that has evolved to capture membrane patches, which then pinch off to become traffic carriers. These carriers are the principal vehicles of receptor-mediated endocytosis and are the major route of traffic from plasma membrane to endosomes. We report here the use of in vivo imaging data, obtained from spinning disk confocal and total in...
متن کاملForty years on: clathrin-coated pits continue to fascinate
Clathrin-mediated endocytosis (CME) is a fundamental process in cell biology and has been extensively investigated over the past several decades. Every cell biologist learns about it at some point during his or her education, and the beauty of this process has led many of us to go deeper and make it the topic of our research. Great progress has been made toward elucidating the mechanisms of CME...
متن کاملPotassium-dependent assembly of coated pits: new coated pits form as planar clathrin lattices
Previous studies have shown that when human fibroblasts are depleted of intracellular K+, coated pits disappear from the cell surface and the receptor-mediated endocytosis of low density lipoprotein (LDL) is inhibited. We have now used the K+ depletion protocol to study several aspects of coated pit function. First, since coated pits rapidly form when K+-depleted fibroblasts are incubated in th...
