What is the role of microtubules in mechanotransduction?

What is the role of microtubules in mechanotransduction? Microtubules exist in all cells, however their influence in the mechanotransduction of mechanical stimuli has been described at length in cardiac striated muscle [1]. Mechanical stimuli [...]

What are Contractile Fibers?

What are Contractile Fibers? Certain myosin isoforms (i.e. myosin II) form bipolar assemblies via the extended coiled-coil domains in the heavy chains (see also “thick filaments”). Actin “thin filaments” with opposite polarity associate with [...]

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 is Actomyosin?

What is Actomyosin? Actomyosin refers to the actin-myosin complex that forms within the cytoskeleton. Actomyosin is inherently contractile, with the myosin motor protein able to pull on actin filaments. This property gives rise to [...]

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 [...]
