How is actomoysin contractility regulated?

How does the contractome protein network regulate actomyosin contractility? Non-muscle myosin II isoforms have a similar structure and function to their muscle equivalents. However, their interaction with actin serves to generate cellular forces rather [...]

What are Blebs?

What are Blebs? Blebs are blister-like protrusions that occur at the cell surface (reviewed in [1]). Blebs form, and function, in a series of defined steps. They typically grow to a length of around [...]

What are lamellipodia and lamella?

What are lamellipodia and lamella? The lamellipodia and lamella are plate-like extensions of the cell that play crucial roles in both cell motility and migration, and mechanosensing. These structures form and function over distinct [...]

How do filopodia move dynamically?

What causes filopodia retraction and collapse? Binding of filopodia to certain ligands or substratum may hinder filament assembly, thereby leading to changes that promote retraction, collapse or growth cone turning [1][2]. For example, substrate [...]

How do filopodia pull on a substrate?

How do filopodia pull on a substrate? Although a reterograde motion of actin filaments is intrinsic in the formation of filopodia, the forces generated by actin treadmilling are too weak to facilitate the “pulling” [...]

How do filopodia attach to the surrounding substrate?

How do filopodia attach to the surrounding substrate? A diverse array of cellular responses can result when a filopodium makes contact with a ligand or substrate. These responses are dependent on the coupling of [...]
