Regulation of actin filament length
Did you know?
WebThe highly organized arrays of thick and thin filaments found in striated muscles continue to be the subject of studies that yield groundbreaking concepts regarding cell motility. One example is the idea that massive, linearly extended polypeptides function as molecular rulers that set the length of polymeric filaments. Actin filaments that are polymerized in vitro … WebThe changes in actin filament length and the extent of cross-linkage between the filaments may account for the directional extension of actin-rich lamellae and contraction of the tail …
WebApr 21, 2015 · Finally, the proteins ADF and AIP1, which both mediate actin filament severing, contribute to stereocilia length maintenance. Altogether, the data support a model whereby stereocilia actin cores are largely static, with dynamic regulation at the tips to maintain a critical length. WebCyclin-dependent kinase 1 activity also was found to regulate cable assembly in vivo. Here we present evidence that formin cell-cycle regulation is conserved in vertebrates. The use of the cable-reconstitution system to test roles for the key actin-binding proteins tropomyosin, capping protein, and cofilin provided important insights into ...
