Protein sorting pathway
WebbThis endosomal maturation pathway is also used to deliver membrane proteins (e.g. signaling receptors) from the plasma membrane to the lysosome for degradation. Some membrane proteins avoid degradation and are cycled back to the plasma membrane via so-called recycling endosomes. WebbTransport through the endomembrane system. In the ER, proteins fold into their correct shapes, and may also get sugar groups attached to them. Most proteins are then transported to the Golgi apparatus in membrane vesicles. Some proteins, however, need …

Webb29 jan. 2024 · Endosomes are the main sorting station in the endosomal pathway. These compartments are necessary for sorting, recycling and degradation of cargo molecules (Maxfield and McGraw, 2004). Proteins destined for degradation are sorted by the ESCRT complexes (Henne et al., 2011) into multivesicular bodies (MVBs) which are finally fused … Webb11 jan. 2024 · Function Vacuolar protein sorting-associated protein (Vps) are part of E ndosomal S orting C omplex R equired for T ransport ( ESCRT) that performs the topologically unique membrane bending and scission reaction away from the cytoplasm. This process is required for the multivesicular body (MVP) pathway, cytokinesis and HIV …
WebbMVBs contain intraluminal vesicles (ILVs) that are generated by invagination and scission from the limiting membrane of the endosome and mostly are delivered to lysosomes … Webb27 sep. 2024 · The new post-ER quality-control pathway seems to require the vacuolar cargo receptor Vps10, which is functionally similar to the mammalian mannose-6 …

Webb15 okt. 2012 · The retromer complex is a vital element of the endosomal protein sorting machinery that is conserved across all eukaryotes. Retromer is most closely associated with the endosome-to-Golgi retrieval pathway and is necessary to maintain an active pool of hydrolase receptors in the trans-Golgi network.
