Given the growing evidence for potential interactions between components of the actin and microtubule cytoskeletons, we examined the effect of actin filament disassembly on the movement of mitochondria along microtubules in activated coelomocytes. Coelomocytes treated with cytochalasin B (CB), to ...

147 A large number of actin-binding proteins have been identified which regulate actin filament assembly and function in cells, and Table 3.2 highlights those which have been identified in platelets. There are six genes encoding different isoforms of the actin monomer protein (3 α-, 1 β-, ...
Jasplakinolide treatment significantly decreased the speed of chromosome movement during 0–30 min after NEBD (Extended Data Fig. 4c,d) and interfered with chromosome capture in some oocytes (Extended Data Fig. 4e,f). Together, these data establish that dynamic actin filaments are required for ...

It has been suggested that the tethering caused by binding of the N-terminal region of smooth muscle caldesmon (CaD) to myosin and its C-terminal region to actin contributes to the inhibition of actin-filament movement over myosin heads in an in vitro motility assay. However, direct evidence ...

Active pushing is thought to occur through binding of actin monomers to the tip of the filament when the object moves away, thus preventing backward movement, such that the object is driven by Brownian diffusion, with the actin filament dictating a single direction (polymerisation rachett) [1]....
