Microtubules

101.6K
There are three types of cytoskeletal structures in eukaryotic cells—microfilaments, intermediate filaments, and microtubules. With a diameter of about 25 nm, microtubules are the thickest of these fibers. Microtubules carry out a variety of functions that include cell structure and support, transport of organelles, cell motility (movement), and the separation of chromosomes during cell division.

Protein-protein Interfaces

14.8K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Structural Protein Function

30.1K
Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity.  In bones and teeth, it mineralizes to...

Summary
This summary is machine-generated.

The C. elegans tubulin family, essential for cell structure and function, comprises nine α-, six β-, and one γ-tubulin. These proteins form microtubules, critical for cell division, polarity, and neuronal sensation.

Area of Science:

  • Cell Biology
  • Molecular Biology
  • Genetics

Background:

  • Tubulins are highly conserved proteins forming α-β heterodimers essential for microtubule assembly.
  • Microtubules are ubiquitous cytoskeletal components critical for cellular and developmental processes.
  • The nematode C. elegans serves as a model organism for studying microtubule functions.

Purpose of the Study:

  • To review the composition and conserved functions of the tubulin family in C. elegans.
  • To highlight the diverse roles of tubulin and microtubules in cellular processes and development.
  • To emphasize the regulatory mechanisms and associated proteins influencing tubulin and microtubule dynamics.

Main Methods:

  • Genetic studies in C. elegans to investigate tubulin function.
  • Cytological analyses to visualize microtubule structures and dynamics.
  • Review of existing literature on tubulin and microtubule biology in C. elegans.

Main Results:

  • C. elegans possesses nine α-, six β-, and one γ-tubulin, forming essential microtubule structures.
  • Tubulin and microtubules are implicated in chromosome segregation, cellular polarity, and neuronal sensation.
  • Interactions with numerous proteins regulate tubulin homeostasis and microtubule dynamics.

Conclusions:

  • The C. elegans tubulin system is crucial for a wide range of biological processes from embryogenesis to adult behavior.
  • Post-translational modifications of tubulins add regulatory complexity to microtubule functions.
  • C. elegans remains a valuable model for dissecting microtubule-associated protein functions and their roles in development and disease.
