4) reduces the affinity of the receptor and apotransferrin for each other and the apotransferrin is released. The apotransferrin is now free to bind more Fe3+ and the receptor is available to bind ferrotransferrin. Receptors are often recycled back to the plasma membrane in vesicles, as with the ferrotransferrin receptor, but this is not always the case. In some instances they are degraded. Caveolin-coated vesicles arise from small flask-shaped invaginations called caveolae present in the plasma membrane of many cell types (Fig.

On binding to the SNAP-SNARE complexes, NSF hydrolyses ATP and is then released. It is thought that the free energy of hydrolysis drives the fusion of vesicle and membrane, although the specific proteins involved and the biophysical mechanism by which fusion occurs are not known. A complex of NSF, SNAPs and SNAREs and other proteins can be extracted from membranes with non-ionic detergents and isolated using a centrifuge as a 'fusion particle' with a sedimentation coefficient of 20s (Fig. 54). The fusion particle is thought to be a general device for facilitating the fusion of all types of coatomer-coated vesicles and their target membranes.
