Actin and microtubule cytoskeleton interactions

Current Opinion in Plant Biology, 2009
Plant cytoskeleton consists of two major networks of protein polymers, actin microfilaments (AFs) and microtubules (MTs). These networks perform numerous functions that are essential for cell division and for maintaining the integrity of cytoplasm required for intracellular transport and cell shape. Besides the more or less indirect cooperation between

Role of actin cytoskeleton in podocytes

Pediatric Nephrology, 2020
The selectivity of the glomerular filter is established by physical, chemical, and signaling interplay among its three core constituents: glomerular endothelial cells, the glomerular basement membrane, and podocytes. Functional impairment or injury of any of these three components can lead to proteinuria.

Prokaryotic origin of the actin cytoskeleton

Nature, 2001
It was thought until recently that bacteria lack the actin or tubulin filament networks that organize eukaryotic cytoplasm. However, we show here that the bacterial MreB protein assembles into filaments with a subunit repeat similar to that of F-actin-the physiological polymer of eukaryotic actin.

Apoptosis and the yeast actin cytoskeleton

Cell Death & Differentiation, 2009
Actin represents one of the most abundant and extensively studied proteins found in eukaryotic cells. It has been identified as a major target for destruction during the process of apoptosis. Recent research has also highlighted a role for cytoskeletal components in the initiation and inhibition of apoptotic processes.

Membrane interactions with the actin cytoskeleton

Current Opinion in Cell Biology, 1994
Recent advances have been made in our understanding of the direct binding of actin to integral membrane proteins. New information has been obtained about indirect actin-membrane associations through spectrin superfamily members and through proteins at the cytoplasmic surfaces of focal contacts and adherens junctions.

Cellular Ageing and the Actin Cytoskeleton

2011
For some time the view that the actin cytoskeleton acts primarily as a scaffold, to be assembled in response to a signaling cascade as an end point in the pathway, has prevailed. However, it is now clear that the dynamic nature of the cytoskeleton is linked to downstream signaling events that further modulate cellular activity, and which can determine ...

Rho GTPases and the Actin Cytoskeleton

Science, 1998
The 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

Functional design in the actin cytoskeleton

Current Opinion in Cell Biology, 1999
Changes 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 ...

Actin cytoskeleton and sperm function

Biochemical and Biophysical Research Communications, 2018
For 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, 1994
Like 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.
