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 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 [...]

Actin Crosslinking

Actin Crosslinking Crosslinking of actin filaments is a critical step in cell motility and is a fundamental process in filopodia protrusion and lamellipodia formation. Smaller cross-linking proteins that are more globular (e.g. fascin) [...]

What are microtubules?

What are microtubules? Microtubules are hollow cylinders [1] that are approximately 25nm in diameter [2] and vary in length from 200 nm to 25 μm. They are formed by the lateral association of between [...]

What are intermediate filaments?

What are intermediate filaments? Intermediate filaments are a primary component of the cytoskeleton, although they are not found in all eukaryotes, and are absent in fungi and plants [1]. These filaments, which extend throughout [...]

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 [...]
