How do actin filaments act as a force-sensing conduit for both internal and external forces?
How do actin filaments act as a force-sensing conduit for both internal and external forces? Internal forces The orientation of individual actin filaments in the cytoskeleton is a force-driven evolutionary process [1] that contributes [...]
How do actin filaments depolymerize?
How do actin filaments depolymerize? Introduction to Actin Filament Depolymerization Whole cell motility and mechanosensing rely on the continual restructuring of the cytoskeleton, particularly within lamellipodia and filopodia; two dynamic structures that contribute to [...]
How does Arp2/3-mediate the nucleation of branched filaments?
How does Arp2/3-mediate the nucleation of branched filaments? The Arp2/3 complex is composed of 7 evolutionarily conserved subunits (Arp2, Arp3, ARPC1-C5) that are structurally similar to the barbed end of actin [1]. The complex [...]
How do actin filaments grow?
How do actin filaments grow? Actin Filaments (F-actin) grow from the polymerization of G-actin monomers Actin is a highly abundant (10-100 micromolar on average),~42 kDa structural protein found in all eukaryotic cells (except for [...]
What are the functions of actin filaments?
What are the functions of actin filaments? Several biological processes related to cell shape and movement depend on actin filaments (reviewed in [1]). Some keys functions are: To form the dynamic cytoskeleton, which gives [...]
What is actin nucleation?
What is actin nucleation? The first step in actin polymerization is known as ‘nucleation’. This step sees the formation of an actin nucleus, which is essentially a complex of three actin monomers, from which [...]
