Summary
The FEAR network and Cdc14 phosphatase in budding yeast coordinate anaphase events, ensuring genomic stability. This complex regulation is crucial for cell cycle progression and accurate DNA segregation during cell division.
Area of Science:
- Cell Biology
- Molecular Biology
- Genetics
Background:
- Anaphase is a critical cell cycle stage involving genome separation.
- Regulation of anaphase is complex due to its irreversible nature.
- The Cdc fourteen early anaphase release (FEAR) network and Cdc14 phosphatase are key regulators in budding yeast.
Purpose of the Study:
- To elucidate the role of the FEAR network and Cdc14 in coordinating anaphase events.
- To understand how these factors contribute to genomic stability.
- To investigate the initiation of mitotic exit during anaphase.
Main Methods:
- The study focuses on the budding yeast model system.
- Investigates the signaling network involving FEAR and Cdc14.
- Analyzes the coordination of DNA partitioning, spindle stability, and microtubule forces.
Main Results:
- The FEAR network and Cdc14 orchestrate multiple anaphase processes.
- These include DNA segregation, spindle regulation, and microtubule dynamics.
- They are essential for initiating mitotic exit.
Conclusions:
- The FEAR network and Cdc14 are vital for successful anaphase completion.
- Their coordinated action ensures genomic stability.
- This regulatory mechanism is fundamental for accurate cell division.

02:36DNA Damage can Stall the Cell Cycle
In response to DNA damage, cells can pause the cell cycle to assess and repair the breaks. However, the cell must check the DNA at certain critical stages during the cell cycle. If the cell cycle pauses before DNA replication, the cells will contain twice the amount of DNA. On the other hand, if cells arrest after DNA replication but before mitosis, they will contain four times the normal amount of DNA. With a host of specialized proteins at their disposal,cells must use the right protein at...
02:17Separation of Sister Chromatids
At the transition from prophase to metaphase, there is a reduction in cohesion along the chromosomal arms, resulting in the resolution of sister chromatids. However, residual cohesin connections remain to hold the sister chromatids together until the transition from metaphase to anaphase. The residual connection prevents any premature separation of sister chromatids, blocking the risks of aneuploidy within the daughter cells.

02:19The Spindle Assembly Checkpoint
The spindle assembly checkpoint is a molecular surveillance mechanism ensuring the fidelity of chromosome segregation during anaphase. The checkpoint monitors the completion of all the prerequisite steps before chromosome segregation to determine whether the segregation process should proceed or be delayed.
Many proteins function together to control the spindle assembly checkpoint. Mutations affecting these proteins may allow cells to proceed into anaphase prematurely, resulting in the...

00:50Anaphase Promoting Complex
The stepwise destruction of specific proteins is necessary for the progression and completion of the cell cycle. Such proteins are ubiquitinated by ubiquitin ligases and then subsequently destroyed by the proteasome. The SCF (Skp1/Cullin/F-box) and the anaphase-promoting complex (APC) are two important ubiquitin ligases involved in cell cycle progression. While SCF is active throughout the cell cycle, APC gets activated during metaphase to anaphase transition. Cdc20 or Cdh1 binds to APC and...
