Recent studies have highlighted the importance of monolayer and bilayer curvature for the budding and fission of biological membranes. Other lines of research, addressing the structure of planar biological membranes, have revealed the existence of cholesterol-based membrane microdomains. Here, we comment on the significance of microdomains for curved membranes, with special emphasis on budding and...
A synthetic N-myristoylated peptide corresponding to the amino-terminal domain of ADP-ribosylation factor 1 (ARF1) markedly increases, in a cell-free system using post-nuclear supernatant from PC12 cells, the biogenesis of constitutive secretory vesicles and immature secretory granules from the trans-Golgi network (TGN). The related N-myristoylated ARF4 peptide only weakly stimulates, and the non-myristoylated...
