Summary
The anaphase-promoting complex/cyclosome (APC/C) with its activator Cdh1 plays crucial roles beyond the cell cycle. Understanding APC/Cdh1 is vital for insights into genomic integrity, differentiation, and human diseases.
Area of Science:
- Cell Biology
- Molecular Biology
- Biochemistry
Background:
- The anaphase-promoting complex/cyclosome (APC/C) is a key ubiquitin ligase regulating protein degradation.
- APC/C activation relies on co-activators Cdc20 and Cdh1.
- APC/Cdc20 primarily controls mitotic progression, while APC/Cdh1 has broader functions.
Purpose of the Study:
- To review the expanded understanding of APC/Cdh1's biological functions.
- To explore the role of APC/Cdh1 in processes beyond the cell cycle.
- To summarize how APC/Cdh1 dysfunction contributes to human diseases.
Main Methods:
- Literature review of biochemical studies.
- Analysis of mouse genetic studies.
- Synthesis of recent research findings.
Main Results:
- APC/Cdh1 regulates a wide array of substrates both within and outside the cell cycle.
- Emerging evidence highlights APC/Cdh1's involvement in maintaining genomic integrity.
- APC/Cdh1 is implicated in cellular differentiation processes.
Conclusions:
- APC/Cdh1 is a critical regulator with significant roles in fundamental biological processes.
- Dysregulation of APC/Cdh1 is linked to the pathogenesis of various human diseases.
- Further research into APC/Cdh1 mechanisms is essential for therapeutic development.

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...

01:28The Cell Cycle Control System
The cell cycle regulation directs how a cell proceeds from one phase to the next and begins mitosis. The cell cycle control system includes intracellular regulatory molecules and external triggers. They provide "stop" or "advance" signals and operate at specific cell cycle stages termed checkpoints to ensure that a particular process is completed before the cell advances to the next phase.

02:11The Cell Cycle Control System
The cell cycle is an organized set of events that leads the cell to divide into two daughter cells, each containing chromosomes identical to the parent cell. It is the cell cycle that leads to the formation of an entire organism from a single-cell zygote. Besides, cell division also functions in the renewal or repair of tissues in adult multicellular eukaryotes. For example, in the bone marrow, the stem cells divide to form new blood cells. Although essential for several functions, cell...

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.
