Summary
A protein complex forms stepwise at the top of Drosophila neuroblasts, organizing cell polarity during division. This complex may function through G-protein signaling pathways.
Area of Science:
- Developmental biology
- Cell biology
- Neuroscience
Background:
- Drosophila neuroblasts exhibit asymmetric cell division.
- Apical-basal polarity is crucial for asymmetric cell division.
- Protein complex assembly at the apical pole is observed.
Purpose of the Study:
- To investigate the assembly and function of a protein complex in Drosophila neuroblasts.
- To understand how this complex organizes apical-basal polarity.
- To explore the potential role of G-protein signaling in this process.
Main Methods:
- Stepwise assembly analysis of protein complexes.
- Polarity organization studies in neuroblasts.
- Investigation of G-protein signaling pathways.
Main Results:
- A protein complex is assembled in a step-wise manner at the apical pole.
- This complex organizes the apical-basal polarity of neuroblasts.
- Evidence suggests a potential role for G-protein signaling.
Conclusions:
- The identified protein complex plays a key role in establishing polarity in dividing neuroblasts.
- The findings provide insights into the mechanisms of asymmetric cell division.
- G-protein signaling is a potential pathway involved in this polarity establishment.

01:18Polarity of the Cytoskeleton
The intrinsic polarity of cells can be primarily attributed to two factors- i) the asymmetric accumulation of mobile components such are regulatory molecules and subcellular components across the cell and ii) the orientation of polar cytoskeletal filaments that make up the cytoskeletal networks, specifically microfilaments, and microtubules arranged along the axis of polarity. Interactions between the cytoskeletal filaments are crucial for the establishment and maintenance of the polar nature...
02:57Attachment of Sister Chromatids
As cells progress into mitosis, the nuclear envelope breaks down, and the condensed chromosomes are exposed to the array of bipolar microtubules of the mitotic spindle. The kinetochore, a large, disc-shaped protein complex, is present at the centromere region of the sister chromatids and acts as a binding site for the microtubules. Usually, the plus-end of a single microtubule is embedded within the kinetochore. However, some kinetochores first establish lateral contact with the side-wall of a...
02:11Forces Acting on Chromosomes
During mitosis, chromosome movements occur through the interplay of multiple piconewton level forces. In prometaphase, these forces help in chromosome assembly or congression at the equatorial plane, eventually leading to their alignment at the metaphase plate. The forces acting on the chromosomes are space and time-dependent; therefore, they vary with the position of the chromosomes as the cell progresses through mitosis.

01:39Mechanism of Filopodia Formation
Filopodia are thin, actin-rich cellular protrusions that play an important role in many fundamental cellular functions. They vary in their occurrence, length, and positioning in different cell types, suggesting their diverse roles.
Their main function is to guide migrating cells during normal tissue morphogenesis or cancer metastasis by recognizing and making initial contacts with the extracellular matrix. However, they can also act as stationary cell anchors or help to establish communication...

01:21Cell Polarization by Rho Proteins
Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is essential to many processes such as embryogenesis, axon migration, glucose transport across epithelial cells, and directional cell migration. A migrating cell responds to intracellular or extracellular signals via molecular cascades that reorganize the actin cytoskeleton to establish this polarity. In these cells, the Rho family proteins Cdc42,...
01:32Cytoskeletal Coordination in Cell Migration
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker proteins that...
