Summary
Tubulin, the main protein in the mammalian brain, forms microtubules essential for neuronal functions like neurite outgrowth and transport. Understanding tubulin expression and microtubule dynamics is key to deciphering complex brain activities.
Area of Science:
- Neuroscience
- Cell Biology
Background:
- Tubulin is the most abundant protein in the mammalian brain.
- Microtubules, formed by tubulin, are critical organelles involved in neuronal function.
Purpose of the Study:
- To review the relationship between microtubule structure and function.
- To explore the regulatory mechanisms of tubulin expression.
- To elucidate the role of microtubules in complex neuronal functions.
Main Methods:
- Literature review of studies on tubulin and microtubules.
- Analysis of microtubule structure-function relationships.
- Examination of tubulin gene expression control.
Main Results:
- Microtubule integrity is crucial for neurite outgrowth, axoplasmic transport, and synaptic function.
- Tubulin dynamics and expression are tightly regulated.
- These processes are fundamental to higher-order neuronal activities.
Conclusions:
- Microtubules play a vital role in fundamental neuronal processes.
- Further research into tubulin regulation can illuminate complex brain functions.
- This review synthesizes current knowledge on tubulin and neuronal plasticity.

01:32Assembly of Complex Microtubule Structures
Complex microtubule structures are present in resting cells and in dividing cells. In resting cells, they are responsible for maintaining the cellular architecture, tracks for intracellular transport, positioning of organelles, assembly of cilia and flagella. They mediate the bipolar spindle assembly for chromosomal segregation and positioning of the cell division plate in dividing cells. The formation of microtubule complex structures depends on the cell type, cell stage, and cell function.
01:23Microtubule Formation
Microtubules are dynamic structures that undergo continuous assembly and disassembly. They originate from specialized multi-protein complexes known as microtubule organizing centers or MTOCs. Within the MTOC, the point of origin of the microtubule is known as the minus end, while the end radiating outward is the plus end. Microtubules serve two primary functions — the organization of spindle complexes to separate sister chromatids during mitotic or meiotic cell division and the formation of...
01:31Nervous Tissue: Glial Cells
Glia, or neuroglia, are vital support cells that assist neurons in their functions. The term "glia" originates from the Greek word for "glue," reflecting their role in holding the nervous system together. These cells can be categorized into six types: four in the central nervous system (CNS) and two in the peripheral nervous system (PNS).
The CNS glial cell includes the astrocytes, the oligodendrocytes, the microglia, and the ependymal cells.

01:18Microtubules
Microtubules are the thickest cytoskeletal filaments with a diameter of 25 nm. In prokaryotic organisms, microtubules are commonly found in locomotory appendages like cilia and flagella. In eukaryotic cells, microtubules form specialized extensions for moving fluid over the surface, like those found in cells lining the intestine.
Microtubules have two structurally similar globular protein subunits: α and β tubulins. In the cytosol, the α and β tubulins form a heterodimer. These αβ-heterodimers...

01:35Microtubules
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.Microtubules are hollow tubes whose walls are made up of globular tubulin proteins. Each tubulin...
02:17Microtubule Instability
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated assembly and...
