Functional design in the actin cytoskeleton
Current Opinion in Cell Biology, 1999Changes in cell shape, anchorage and motility are all associated with the dynamic reorganisation of the architectural arrays of actin filaments that make up the actin cytoskeleton. The relative expression of these functionally different actin filament arrays is intimately linked to the pattern of contacts that a cell develops with its extracellular ...

Rho GTPases and the Actin Cytoskeleton
Science, 1998The actin cytoskeleton mediates a variety of essential biological functions in all eukaryotic cells. In addition to providing a structural framework around which cell shape and polarity are defined, its dynamic properties provide the driving force for cells to move and to divide. Understanding the biochemical mechanisms that control the organization of

Actin cytoskeleton and sperm function
Biochemical and Biophysical Research Communications, 2018For the acquisition of the ability to fertilize the egg, mammalian spermatozoa should undergo a series of biochemical transformations in the female reproductive tract, collectively called capacitation. The capacitated sperm can undergo the acrosomal exocytosis process near or on the oocyte, which allows the spermatozoon to penetrate and fertilize it ...

Actin Cytoskeleton: Through the bottleneck
Current Biology, 1994Like serendipity-alpha and nullo, the newly characterized gene bottleneck is involved in organizing the actin cytoskeleton of the Drosophila embryo to achieve the transition from a syncytium to a cellular blastoderm.

Actin cytoskeleton and cell signaling
Critical Care Medicine, 2000The role of the actin cytoskeleton in the function of eukaryotic cells is ubiquitous. Regulation of actin polymerization allows cells to control their shape, to move, divide, secrete, and phagocytose. Actin filaments provide strength, connections to other cells and the extracellular matrix, paths for intracellular transport and a scaffold for ...

Baculovirus Infectivity and the Actin Cytoskeleton
Current Drug Targets, 2007Baculovirus infection occurs when susceptible insect larvae ingest viral occlusions and occlusion-derived virus is released in the midgut lumen. Midgut columnar epithelial cells (the sole targets) are penetrated when the viral envelopes fuse with microvillar membranes; subsequently, nucleocapsids are transported basally through the microvilli toward ...

The actin cytoskeleton in memory formation
Progress in Neurobiology, 2014The ability to efficiently store memories in the brain is a fundamental process and its impairment is associated with multiple human mental disorders. Evidence indicates that long-term memory (LTM) formation involves alterations of synaptic efficacy produced by modifications in neural transmission and morphology.
