Summary
Microtubule minus ends, once poorly understood, are now known to be regulated by specific targeting proteins. These regulators are crucial for organizing microtubules in various cellular functions.
Area of Science:
- Cell Biology
- Cytoskeletal Dynamics
- Molecular Cell Biology
Background:
- Microtubules are polarized cytoskeletal filaments with distinct plus and minus ends.
- Microtubule plus-end dynamics are well-studied and influenced by plus-end-tracking proteins (+TIPs).
- The regulation of microtubule minus ends remains largely unexplored.
Purpose of the Study:
- To review the current understanding of microtubule minus-end regulation.
- To highlight the role of specific minus-end-targeting proteins (-TIPs) in controlling microtubule behavior.
- To discuss the contribution of minus-end regulators to non-centrosomal microtubule organization and function.
Main Methods:
- Literature review of recent studies on microtubule minus-end dynamics.
- Analysis of the function of CAMSAP/Patronin/Nezha protein family.
- Synthesis of knowledge regarding microtubule minus-end regulation mechanisms.
Main Results:
- The CAMSAP/Patronin/Nezha family acts as specific minus-end-targeting proteins (-TIPs).
- These -TIPs provide crucial insights into the mechanisms governing microtubule minus-end dynamics.
- Minus-end regulators are essential for non-centrosomal microtubule organization.
Conclusions:
- Understanding microtubule minus-end regulation is critical for comprehending microtubule cytoskeleton function.
- -TIPs are key players in controlling microtubule minus-end dynamics and organization.
- Minus-end regulation impacts vital cellular processes including cell division, migration, and differentiation.

Microtubule Associated Proteins (MAPs)
6.4K
Microtubule function and architecture are regulated by an array of specialized proteins called microtubule-associated proteins or MAPs. These proteins are widespread across different organisms and have conserved protein motifs, like the multi-TOG domain for tubulin binding found in the CLASP family of MAPs. Some MAPs are lineage-specific based on their conserved domains. Their functions depend upon the cytoskeletal architecture and cell type they are located within. In-plant cells, a specific...

Microtubule Associated Motor Proteins
11.8K
Eukaryotic cells have different motor proteins for transporting various cargo within the cell. These motor proteins differ based on the filament they associate with, the direction they move within the cell, and the type of cargo they transport. Motor proteins that associate with microtubules are known as microtubule-associated motor proteins. There are two families of microtubule-associated motor proteins —Kinesins and Dyneins. Both these proteins assist in the transport of cellular...

Anaphase A and B

Microtubules form through the end-to-end polymerization of tubulin heterodimers. Kinetochore microtubules originate from the spindle poles, and their plus-ends connect with the kinetochores on sister-chromatids. Ndc80 protein complexes, present on the kinetochore, form low-affinity links with the plus end of these kinetochore microtubules.
Plus-end depolymerization releases tubulin heterodimers from the terminal region of the microtubule. As tubulin subunits are lost, the Ndc80 complexes detach...

Microtubule Formation
8.2K
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...

Microtubules

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....

Microtubules

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.
