Webb5 mars 2024 · The binding of a signal molecule by the extracellular part of the G-protein linked receptor causes the cytosolic tail of the receptor to interact with, and alter the conformation of, a G-protein. This has two consequences: First, the alpha subunit of the G- protein loses its GDP and binds a GTP instead.

Webb17 jan. 2013 · The mechanism of protein targeting to the peroxisomes is referred to the recent reviews in Refs 6 and 8. We mainly focus on cytosolic events for three types of proteins: proteins that are imported into organelles, proteins targeted to outer envelope membranes (OEMs) with signal-anchor or tail-anchor. WebbThe collection of these proteins starts to curve the adjacent section of the membrane that eventually pinches off to form an internalized coated vesicle. Clathrin and dynamin then recycle back to the plasma membrane, leaving an uncoated vesicle that is free to fuse with an early endosome.
