Web4 Mar 2024 · However, the role of actin in the exo- and endocytosis of secretory cells remained not well understood despite it being one of the most abundant cytoskeletal proteins (Cingolani and Goda, 2008; Li et al., 2024). Studies over the past three decades led to proposals that actin is involved in many steps of exo- and endocytosis in secretory cells. Web1 Feb 2006 · Roles of actin As detailed above there are a large number of different phenotypes that arise upon mutation of the actin gene in yeast suggesting that F-actin plays a number of roles. These include morphogenesis, mitosis, meiosis, cytokinesis and septation, and the movement and positioning of organelles.
WebFluorescence redistribution after photobleaching (FRAP) was used to examine the role of actin and myosin in the transport of dextrans through the nuclear pore complex. Anti-actin antibodies added to isolated rat liver nuclei significantly reduced the flux rate of fluorescently labeled 64-kD dextrans. The addition of 3 mM ATP to nuclei, which ... WebThe actin is attached to the ends of sarcomeres (Z bands, unless I am mistaken). These bands are then in series with whatever force is being applied on the muscle and transmit this force onto the attached actin. ...
