26 de oct. de 2022 · The dynamic turnover of actin filaments (F-actin) controls cellular motility in eukaryotes and is coupled to changes in the F-actin nucleotide state1–3. It remains unclear how F-actin hydrolyses ...

6 de oct. de 2020 · In cell biology, self-organization is thought to regulate the assembly of several important cellular structures, including the mitotic spindle, the nucleolus, and the actin and microtubule cytoskeletons, thereby mediating many essential cellular processes ( Dundr et al., 2000; Glick, 2002; Heald et al., 1996; Karsenti and Vernos, 2001 ).

Divalent Cations, Nucleotides and Actin Structure. Hanna Strzelecka-Golaszewska provides us with an insightful summary of the binding affinity and kinetic behaviour of actin’s ligands (nucleotide and metal cation). These changes are examined in relation to changes in the domain structure of actin.
11 de nov. de 2009 · Actin is essential for the survival of most cells: filaments provide internal mechanical support, tracks for movements of intracellular materials and force to drive cell movements. Many modern species of prokaryotes use actin relatives to maintain asymmetrical shapes and to move DNA through the cytoplasm.

Since the main goal of this review is to bring to light how the dynamics and the mechanics of actin structures control their physiology in the cell, we will focus our attention on the four different types of actin architecture depicted in Figure 1 A that have well-documented mechano-biology.

22 de nov. de 2016 · Seven decades of research have revealed much about actin structure, assembly, regulatory proteins, and cellular functions. However, some key information is still missing, so we do not understand the mechanisms of most processes that depend on actin. This chapter...
