Summary
Septins, initially known for cell division, are now recognized for their roles in microtubule dynamics and cell structure. Understanding septin-microtubule interactions is key for developing therapies for diseases like cancer and neurodegeneration.
Area of Science:
- Cell Biology
- Cytoskeletal Dynamics
Background:
- Septins were initially identified as regulators of cytokinesis (cell division).
- Emerging evidence indicates septins participate in a wider array of cellular functions.
- These functions include nuclear division (karyokinesis), secretion (exocytosis), and cell shape maintenance.
Purpose of the Study:
- To explore the broader roles of septins beyond cytokinesis.
- To investigate the interaction of septins with the microtubule cytoskeleton.
- To understand the implications of septin biology in disease.
Main Methods:
- Colocalization studies to observe septin and microtubule proximity.
- Interaction studies to identify molecular connections between septins and microtubules.
- Analysis of septin involvement in microtubule-dependent cellular processes.
Main Results:
- Septins colocalize and interact with the microtubule cytoskeleton.
- Septins influence microtubule dynamics, potentially by interacting with microtubule-associated proteins (MAPs).
- Septins act as adaptors between actin and microtubule cytoskeletons.
Conclusions:
- Septins possess diverse functions linked to the microtubule cytoskeleton.
- Septin-microtubule interactions are crucial for cellular processes.
- Further research into septin biology may offer therapeutic strategies for neurodegenerative diseases and cancer.

01:02Role of Septins
Septins are the recently discovered fourth major protein component of the cytoskeleton, along with microfilaments, microtubules, and intermediate filaments. These proteins can associate with other cytoskeletal filaments and carry out varied roles or can be free-floating in the cytoplasm.
Cellular Functions of Septins
Recent studies have revealed the multifaceted roles of septins in various cellular processes such as cytokinesis, ciliogenesis, and neurogenesis. Septins act as scaffolds and...

01:19Septins
Septins are protein filaments forming the cytoskeleton along with the microtubules, microfilaments, intermediate filaments, and other accessory proteins. In 1971 while studying the cell division cycle in mutant Saccharomyces cerevisiae Harwell et al. first identified the septin-related genes playing a crucial role in yeast cytokinesis. Fluorescence microscopy revealed that these proteins localize at the budding neck as rings. These ring-like proteins were then named Septins by John Pringle, and...
01:42Microtubule Associated Proteins (MAPs)
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...
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...
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...
