Clathrin-mediated endocytosis is inhibited during mitosis.
A long-standing paradigm in cell biology is the shutdown of endocytosis during mitosis. There is consensus that transferrin uptake is inhibited after entry into prophase and that it resumes in telophase. A recent study proposed that endocytosis is continuous throughout the cell cycle and that the observed inhibition of transferrin uptake is due to a decrease in available transferrin receptor at...
متن کاملClathrin exchange during clathrin-mediated endocytosis
During clathrin-mediated endocytosis, clathrin-coated pits invaginate to form clathrin-coated vesicles (CVs). Since clathrin-coated pits are planar structures, whereas CVs are spherical, there must be a structural rearrangement of clathrin as invagination occurs. This could occur through simple addition of clathrin triskelions to the edges of growing clathrin-coated pits with very little exchan...
متن کاملConstitutive Clathrin-mediated Endocytosis of CTLA-4 Persists during T Cell Activation
CTLA-4 is one of the most important negative regulators of the T cell immune response. However, the subcellular distribution of CTLA-4 is unusual for a receptor that interacts with cell surface transmembrane ligands in that CTLA-4 is rapidly internalized from the plasma membrane. It has been proposed that T cell activation can lead to stabilization of CTLA-4 expression at the cell surface. Here...
متن کاملMonitoring clathrin-mediated endocytosis during synaptic activity.
To visualize clathrin redistribution during endocytosis in hippocampal boutons, we used a fusion protein of clathrin light chain with enhanced green fluorescent protein. Both high potassium and electric field stimulation lead after a stimulus-dependent delay to a transient increase of fluorescence in synapses, but a slight and transient decrease in adjacent axonal segments. We conclude that the...
متن کاملKinases in clathrin-mediated endocytosis.
The process of clathrin-coated vesicle (CCV) formation/disassembly has been studied intensively, and numerous proteins have been identified which aid this process. We have learnt a great deal about individual components of the CCV machinery, and now the ultimate aim is to elucidate the mechanisms regulating clathrin-mediated trafficking. One of the fundamental processes governing the complicate...
