Formins at a glance - PMC Formins are conserved actin polymerization machines that have instrumental roles in controlling rearrangements of the actin cytoskeleton and have recently been shown to directly regulate microtubule dynamics
Mechanisms of actin filament severing and elongation by formins Cryo-electron microscopy shows five structural states of inverted formin 2 and two of formin diaphanous 1 bound to F-actin, providing step-by-step visualization of the mechanisms of F-actin
Formins at a glance Free - The Company of Biologists Formins are conserved actin polymerization machines that have instrumental roles in controlling rearrangements of the actin cytoskeleton and have recently been shown to directly regulate microtubule dynamics
Molecular mechanism of actin filament elongation by formins Formins are highly conserved actin end-binding proteins By recruiting actin monomers and moving with the fast-growing ends of filaments, formins act as polymerases that control actin dynamics in many biological processes The human genome encodes 15 distinct formins, which drive filament growth with different speeds
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 of actin nucleation, a process which is spatiotemporally coupled with actin disassembly [1] This schematic diagram illustrates the molecular organization of formin
Mechanisms of formin-mediated actin assembly and dynamics Here, I review recent biophysical, structural, and computational studies that have provided insight into the mechanisms of formin-mediated actin assembly and dynamics Keywords: Formin, Actin, Profilin, Polymerization
Formin: The Multidomain Elongator of Actin Polymer Formin is a multidomain, mega-dalton protein, which is essentially an important regulator of actin polymerization in eukaryotes In this chapter we review various domains of formin that have been reported in the literature for various organisms We also report a
