What is the role of cortactin in actin polymerization?
What is the role of cortactin in actin polymerization? Cortactin is a class II nucleation promoting factor (NPF) that binds to actin filaments and influences their stability. Cortactin specifically stabilizes Arp2/3-mediated branch points along [...]
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 [...]
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 factors regulate actin filament polymerization?
What factors regulate actin filament polymerization? Nucleation Promoting Factors (NPFs) (e.g. WASP, Scar/WAVE) modulate actin filament nucleation by bringing together actin monomers and pre-existing actin filaments, for example, during filopodial initiation where they recruit [...]
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, [...]
I-BAR and Other Proteins/Factors
I-BAR and Other Proteins/Factors Proteins containing I-BAR (inverted Bin/amphiphysin/Rvs i.e. IRSp53 Missing-in-metastasis homology Domain or IMD) cooperate with various components of actin filament assembly, to promote filopodia protrusion, via several mechanisms including the stimulation [...]
