Scale dependence of mechanics and dynamics of active gels with increasing motor concentration [PDF]
, 2016 The cytoskeleton protein actin assembles into large bundles when supporting stresses in the cell, but grows into a fine branched network to induce cell motion. Such self-organization processes are studied in artificial networks of cytoskeleton proteins with thick actin bundles and large motor protein aggregates to enable optical observation. The effect

Interactions of mitochondria with the actin cytoskeleton
Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2006 Interactions between mitochondria and the cytoskeleton are essential for normal mitochondrial morphology, motility and distribution. While microtubules and their motors have been established as important factors for mitochondrial transport, emerging evidence indicates that mitochondria interact with the actin cytoskeleton in many cell types. In certain

Actin cytoskeleton: Thinking globally, actin’ locally [PDF]
Current Biology, 2000 A class of proteins dubbed pipmodulins bind to and sequester the phospholipid PIP2 in the plasma membrane. Local release of PIP2 controls actin dynamics in specific subcellular regions and plays a critical role in regulating actin-based cell motility and morphogenesis.

Role of actin cytoskeleton in the organization and function of ionotropic glutamate receptors
Current Research in Structural Biology, 2021 Neural networks with precise connection are compulsory for learning and memory. Various cellular events occur during the genesis of dendritic spines to their maturation, synapse formation, stabilization of the synapse, and proper signal transmission. The

An actin‐based cytoskeleton in archaea [PDF]
Molecular Microbiology, 2011 SummaryIn eukaryotic and bacterial cells, spatial organization is dependent upon cytoskeletal filaments. Actin is a main eukaryotic cytoskeletal element, involved in key processes such as cell shape determination, mechanical force generation and cytokinesis.

The Poisson ratio of the cellular actin cortex is frequency-dependent [PDF]
, 2019 Cell shape changes are vital for many physiological processes such as cell proliferation, cell migration and morphogenesis. They emerge from an orchestrated interplay of active cellular force generation and passive cellular force response - both crucially influenced by the actin cytoskeleton.

The actin cytoskeleton in ageing and apoptosis [PDF]
FEMS Yeast Research, 2005 Regulated cell death, or apoptosis, has evolved to fulfil a myriad of functions amongst multicellular organisms. It is now apparent that programmed cell death occurs in unicellular organisms such as yeast. In yeast, as in higher eukaryotes, the actin cytoskeleton is an essential component of a number of cellular activities, and many of the regulatory ...
