In Vitro Nuclear Assembly Using Fractionated Xenopus Egg Extracts
Published on: September 2, 2008
Summary
Singlet microtubules and basal body cartwheel complexes self-assemble from Tetrahymena basal body extracts. This finding provides insights into the self-assembly mechanisms of essential cellular structures.
Area of Science:
- Cell Biology
- Microtubule Dynamics
- Basal Body Formation
Background:
- Basal bodies are crucial for cilia and flagella formation.
- The cartwheel structure is a defining feature of basal bodies.
- Understanding basal body self-assembly is key to deciphering ciliopathies.
Purpose of the Study:
- To investigate the self-assembly potential of basal body components.
- To determine if singlet microtubules and cartwheel structures can form in vitro.
- To explore the role of Tetrahymena basal body extracts in self-assembly.
Main Methods:
- Utilized extracts derived from Tetrahymena basal bodies.
- Observed the self-assembly of microtubule structures.
- Characterized the morphology and dimensions of assembled structures using microscopy.
Main Results:
- Successfully induced self-assembly of singlet microtubules.
- Observed structures with the characteristic morphology and dimensions of the basal body cartwheel complex.
- Demonstrated self-assembly in a cell-free system.
Conclusions:
- Tetrahymena basal body extracts contain components capable of self-assembly.
- Singlet microtubules and cartwheel structures can spontaneously form under specific conditions.
- This supports a model of intrinsic self-assembly for basal body components.

02:41Protein Complex Assembly
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types. Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.

01:18Assembly of Cytoskeletal Filaments
Cytoskeletal filaments are polymeric forms of smaller protein subunits. However, individual cytoskeletal filaments may easily disassemble or associate with other similar filaments to form rigid structures. Microfilaments, made of actin monomers, rely on actin-binding proteins to form bundles and create networks of individual actin filaments. Microtubules rely on microtubule-associated proteins (MAPs) to form sturdy cylindrical structures. However, the proteins involved in forming complex...
02:27The Mitotic Spindle
The mitotic spindle—or spindle apparatus—is a eukaryotic, cytoskeletal structure made up of long protein fibers called microtubules. Formed during cell division, the spindle separates sister chromatids and moves them to opposite ends of a parental cell, where the now individual chromosomes are distributed to two daughter cell nuclei.
The bipolar configuration of the mitotic spindle facilitates chromosomal segregation, preparing the cell for division. One mechanism that ensures bipolar mitotic...

02:50Spindle Assembly
Spindle assembly occurs through three, often coexisting, pathways – the centrosome-mediated pathway, the chromatin-mediated pathway, and the microtubule-mediated pathway – collectively contributing to form a robust spindle apparatus.
In most cells, centrosomes are the primary microtubule nucleation centers. In the centrosome-mediated pathway, the G2-prophase transition triggers centrosome maturation and increased microtubule nucleation. Progressive nucleation results in a microtubule array...

01:35Disassembly of Intermediate Filaments
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.

01:13Centrioles and Centrosomes
Most animal cells comprise a pair of centrioles together called a centrosome. The cell duplicates its centrosome and contains two centrosomes side-by-side, which begin to move apart during the prophase. As the centrosomes migrate to two different sides of the cell, microtubules start extending from each centrosome toward the other end. The mitotic spindle is composed of the centrosomes and their emerging microtubules.
