Alteration of the cortical actin cytoskeleton deregulates Ca2+ signaling, monospermic fertilization, and sperm entry. [PDF]
PLoS ONE, 2008 BackgroundWhen preparing for fertilization, oocytes undergo meiotic maturation during which structural changes occur in the endoplasmic reticulum (ER) that lead to a more efficient calcium response. During meiotic maturation and subsequent fertilization,

Phosphatidylinositol (4,5)-bisphosphate turnover by INP51 regulates the cell wall integrity pathway in "Saccharomyces cerevisiae" [PDF]
, 2004 Signal transduction pathways are important for the cell to transduce external or internal stimuli where second messengers play an important role as mediators of the stimuli. One important group of second messengers are the phosphoinositide family present

NETWORKED 3B: a novel protein in the actin cytoskeleton-endoplasmic reticulum interaction [PDF]
, 2017 In plants movement of the endoplasmic reticulum (ER) is dependent on the actin cytoskeleton. However little is known about proteins that link the ER membrane and the actin cytoskeleton.

Effects of plasma membrane cholesterol level and cytoskeleton F-actin on cell protrusion mechanics. [PDF]
, 2013 Protrusions are deformations that form at the surface of living cells during biological activities such as cell migration. Using combined optical tweezers and fluorescent microscopy, we quantified the mechanical properties of protrusions in adherent ...

When fat is not bad: the regulation of actin dynamics by phospholipid signaling molecules
Frontiers in Plant Science, 2014 The actin cytoskeleton plays a key role in the plant morphogenesis and is involved in polar cell growth, movement of subcellular organelles, cell division, and plant defense.

Mechanical Behavior of Axonal Actin, Spectrin, and Their Periodic Structure: A Brief Review [PDF]
arXiv, 2021 Actin and spectrin are important constituents of axonal cytoskeleton. Periodic actin and spectrin structures are found in dendrites, initial segment of axon, and main axon. Actin and spectrin periodicity has been hypothesized to be manipulating the axon stability and mechanical behavior.
