Distinct acto/myosin-I structures associate with endocytic profiles at the plasma membrane

Abstract: Endocytosis in yeast requires actin and clathrin. Live cell imaging has previously shown that massive actin polymerization occurs concomitant with a slow 200-nm inward movement of the endocytic coat (Kaksonen, M., Y. Sun, and D.G. Drubin. 2003. Cell. 115:475–487). However, the nature of the primary endocytic profile in yeast and how clathrin and actin cooperate to generate an endocytic vesicle is unknown. In this study, we analyze the distribution of nine different proteins involved in endocytic uptake along p… Show more

“…In the wild-type cells, a shallow invagination turns into an elongated vesicle with a constricted neck before scission, which is successfully imaged in experimental studies ( Fig. 1) (14,18,19). In contrast, such an intermediate shape is not observed in BAR mutant cells.…”

“…The yeast amphiphysin homolog, a heterodimeric complex of Rvs161 and Rvs167, is concentrated along the neck of the growing tubule of a deeply invaginated CCP (Idrissi et al, 2008;Kaksonen et al, 2005;Picco et al, 2015). Bzz1, an F-BAR protein of the WASp and myosin module, and Rvs161-Rvs167 have been found to contribute cooperatively to vesicle scission (Kishimoto et al, 2011).…”

“…It is believed that the cortical patches of fibrous actin form around finger-like plasma membrane invaginations, 150-to 250-nm-deep tubular structures with a diameter of ~50 nm (Mulholland et al, 1994) that concentrate in areas of polarized growth. The formation of a finger-like invagination in relation to the endocytic event has been explained in molecular detail by fluorescence (Kaksonen et al, 2005) and electron microscopy (Idrissi et al, 2008) studies. Actin patches and/or finger-like invaginations were also suggested to be places of cell wall synthesis (Kopecka and Gabriel, 1995).…”
