We next used ADA cells to investigate actin assembly at CME sites in live cells, which has several advantages over studies in fixed cells. During the fixation and subsequent sample preparation, actin structures may not be faithfully preserved. In addition, in live cells it is easier to identify the stage of CME, so the timing, … See more To gain additional insights into the function of this asymmetric actin network assembly, we quantitatively compared kinetics of CME events with or without ARPC3 recruitment. … See more To further explore how asymmetric assembly of actin networks at CME sites is regulated, we endogenously tagged N-WASP, an actin … See more WebNov 13, 2024 · The lamellipodial actin network is a dynamic and dense mesh made of short and branched filaments (Svitkina and Borisy, 1999) capable of opposing the front-edge membrane tension and inducing protrusions (Pollard and Borisy, 2003).The Arp2/3 complex is a canonical actin nucleator of the leading edge (Mullins et al., 1998; Svitkina and … furniture stores like american freight https://gumurdul.com

Biochemical data have shown ... WebOur results suggest that Wash is a link between branched actin filaments (associated with Arp2/3) and linear actin filaments (associated with formins and Spire proteins). We are currently exploring how Wash, Spire, and Capu work in the cytoplasm to coordinate actin and microtubule cytoskeleton dynamics required for different developmental events.

WebThe lamellipodium is composed of a branched actin network nucleated by the Arp2/3 complex and stabilized by adhesions to the ECM substrate (82–84). The lamellipodium is followed by a less dynamic and thicker region called the lamella, where actin cross-linking proteins and non-muscle myosin II motors organize the actin network into ...
