Mechanisms of Endocytic Sorting
Endocytosis is important for the regulation of signal transduction and for the movement of essential cellular components from outside the cell to their appropriate intracellular compartment(s). Two established mechanisms of endocytosis are clathrinmediated (CME) and clathrin-independent endocytosis, and they are responsible for internalization of different ligands. In this study, the newly esta...
متن کاملEndocytosis and molecular sorting.
Endocytosis in eukaryotic cells is characterized by the continuous and regulated formation of prolific numbers of membrane vesicles at the plasma membrane. These vesicles come in several different varieties, ranging from the actin-dependent formation of phagosomes involved in particle uptake, to smaller clathrin-coated vesicles responsible for the internalization of extracellular fluid and rece...
متن کاملUbiquitin and endocytic protein sorting.
Ubiquitin plays a fundamental role not only in proteasome-mediated protein degradation but also in the targeting of membrane proteins for degradation inside the lysosome. Ubiquitination provides a key signal for endosomal sorting of membrane proteins into the MVB (multi-vesicular body), which delivers its cargo to the proteolytic interior of the lysosome. Attachment of single ubiquitin molecule...
متن کاملAdapting for endocytosis: roles for endocytic sorting adaptors in directing neural development
Proper cortical development depends on the orchestrated actions of a multitude of guidance receptors and adhesion molecules and their downstream signaling. The levels of these receptors on the surface and their precise locations can greatly affect guidance outcomes. Trafficking of receptors to a particular surface locale and removal by endocytosis thus feed crucially into the final guidance out...
متن کاملPost-endocytic sorting of Plexin-D1 controls signal transduction and development of axonal and vascular circuits
Local endocytic events involving receptors for axon guidance cues play a central role in controlling growth cone behaviour. Yet, little is known about the fate of internalized receptors, and whether the sorting events directing them to distinct endosomal pathways control guidance decisions. Here, we show that the receptor Plexin-D1 contains a sorting motif that interacts with the adaptor protei...
