Summary
The plant actin cytoskeleton influences nuclear shape, positioning, and dynamics. This study details methods to quantify these nuclear properties, enhancing our understanding of actin
Area of Science:
- Plant cell biology
- Cytoskeletal dynamics
- Nuclear architecture
Background:
- The actin cytoskeleton is crucial for nuclear positioning, shape, and dynamics in plant cells.
- A physical link, the linker of nucleoskeleton and cytoskeleton (LINC) complex, connects the actin cytoskeleton to the nucleus.
- Actin's role in regulating nuclear organization, including nuclear invaginations, is an emerging area of research.
Purpose of the Study:
- To provide detailed protocols for quantifying nuclear shape, organization, and dynamics in plant cells.
- To elucidate the contribution of the actin cytoskeleton to nuclear parameters.
- To enable researchers to measure nuclear circularity, deformations, and dynamics.
Main Methods:
- Quantification of nuclear circularity index.
- Measurement of nuclear deformations.
- Determination of nuclear dynamics within plant cells.
Main Results:

Actin Filament Depolymerization
3.2K
Actin filaments (F-actin) are composed of actin subunits. The dissociation of actin monomers can occur from either end of F-actin. The rate of dissociation is faster from the minus-end or the pointed end, where the actin subunits exist with a bound ADP, together known as ADP-actin. The depolymerization of F-actin is aided by proteins, including the actin-depolymerizing factor (ADF) and cofilin family of proteins, gelsolin, and glia maturation factor (GMF).

Generation of Straight or Branched Actin Filaments
3.0K
The straight or branched structure formation of actin filaments is controlled by nucleating proteins such as the formins and Arp2/3 complex. Formin-mediated assembly results in straight filaments, whereas Arp2/3 protein complex-mediated assembly results in branched actin filaments.
Arp2/3 Complex
Arp2/3 complex is a seven-subunit complex consisting of two proteins similar to actin- Arp2 and Arp3, and five other subunits that help keep Arp2 and Arp3 inactive. When required, the complex is...

Actin Polymerization and Cell Motility
5.3K
Actin is a family of globular proteins that are highly abundant in eukaryotic cells. It makes up approximately 1-5% of total cell protein concentration. Actin monomers polymerize to form a complex network of polarized filaments, the actin cytoskeleton, that plays a crucial role in many cellular processes, including cell motility, division, endocytosis, and metastasis of cancer cells.

Actin Polymerization
6.8K
Actin polymerization occurs through the head-to-tail association of binding sites on monomeric actin or G-actin to form filamentous or F-actin. The polymerization can be divided into three phases ̶ nucleation, elongation, and steady-state phase.
The nucleation phase involves forming a stable nucleus consisting of three actin monomers to form a new actin filament. Actin-binding proteins such as formins and Arp2/3 complex help filament growth post-nucleation. The Formins form straight...

Cell Motility through Blebbing
2.0K
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

Disassembly of Intermediate Filaments
2.1K
Intermediate filaments (IFs) do not undergo spontaneous disassembly. Enzymes, kinases, and phosphatases add and remove phosphates from specific sites to regulate their disassembly. The IF concentration in the cytoplasm also regulates the disassembly. If the concentration crosses a threshold, it activates the protein kinases in the vicinity, allowing the phosphorylation of IFs.
