Actin Structure and Function - PMC - PubMed Central (PMC)
We need details of the actin ATPase, detailed structure of ADP F-actin, and detailed structure of ATP F-actin. More accurate structures of the ends of the actin filament (pointed and barbed), …
Actin - Wikipedia
Actin is a family of globular multi-functional proteins that form microfilaments in the cytoskeleton, and the thin filaments in muscle fibrils. It is found in essentially all eukaryotic cells, where it …
Structure and Organization of Actin Filaments
The key protein responsible for actin filament disassembly within the cell is cofilin, which binds to actin filaments and enhances the rate of dissociation of actin monomers from the minus end. …
Actin: Structure, Function, Dynamics, and Interactions with
Nov 16, 2016 · The actin protein is composed of a single polypeptide chain of 375 amino acid residues (skeletal muscle actin) with a molecular mass of 42 kDa, whose sequence was …
Actin Structure and Function: What We Still Do Not Understand
Actin is found in two main states: G-actin (G for globular) is the monomeric form (Fig. 1), whereas F-actin (F for filamentous) is the helical polymer (Fig. 2).
Structures of the free and capped ends of the actin filament
May 25, 2023 · Actin is a key protein in cellular motility, forming filaments that give dynamic structure to cellular appendages and serve as scaffold for motor proteins. The ends of these …
Specification of Architecture and Function of Actin Structures by Actin …
In this review, we explore the role of actin nucleation factors in constructing three different geometries of actin structures: dendritic networks, actin bundles, and isotropic networks …
Molecular Interactions of Actin: Actin Structure and Actin …
Actin is one of the most widespread proteins in eukaryotic cells. This book and its companion (Molecular Interactions of Actin. Actin-Myosin Interaction, Actin-Based Regulation) provide an …
Actin Structure and Function - Annual Reviews
Here we review structures of G-actin and F-actin and discuss some of the interactions that control the polymerization and disassembly of actin. Actin is the most abundant protein in most …
Actin: Structure, Function, Dynamics, and Interactions with ... - PubMed
Here, we describe the structure of monomeric and polymeric actin, the polymerization kinetics, and its regulation by actin-binding proteins. Probably due to its conserved nature and …
