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 [...]
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 [...]
What factors influence actin filament length and treadmilling?
What factors influence actin filament length and treadmilling? Several factors influence actin filament length and treadmilling. ATP binding on G-actin and free ATP-G-actin concentration ATP-binding on actin subunits modulates the dynamics of filament assembly, [...]
What is the steady state phase of actin polymerization?
What is the steady state phase of actin polymerization? In the steady state phase, the filament dynamics enter a state of equilibrium where monomer disassembly from the (-) end and polymerization at the (+) [...]
What is the role of formin in actin polymerization?
What is the role of formin in actin polymerization? Formins promote the elongation of pre-existing filaments by removing barbed end capping proteins and forming a sleeve around the actin subunits. Formins are also capable [...]
