positive regulation of attachment of spindle microtubules to kinetochore
Definition
Target type: biologicalprocess
Any process that activates or increases the frequency, rate or extent of the attachment of spindle microtubules to the kinetochore. [GOC:ai]
Positive regulation of attachment of spindle microtubules to kinetochore is a crucial step in ensuring accurate chromosome segregation during cell division. This process involves a complex interplay of proteins that regulate the dynamic interactions between microtubules and kinetochores. Kinetochores are protein complexes that assemble on centromeric DNA and serve as attachment points for microtubules. The process of positive regulation of attachment of spindle microtubules to kinetochore can be broken down into several key steps:
1. **Microtubule capture:** Microtubules emanating from the spindle poles search for and capture kinetochores. This initial capture is often weak and unstable.
2. **Microtubule stabilization:** Once a microtubule has captured a kinetochore, it needs to be stabilized. This involves a series of events that promote the binding of microtubule-associated proteins (MAPs) to the kinetochore. These MAPs include proteins like CENP-E, dynein, and kinesin-14, which contribute to stabilizing the microtubule-kinetochore interaction.
3. **Tension sensing:** The attachment of a microtubule to a kinetochore generates tension, which is critical for proper chromosome alignment. Tension sensing mechanisms detect this force and signal the kinetochore to further stabilize the attachment.
4. **Checkpoint regulation:** The spindle assembly checkpoint (SAC) ensures that all chromosomes are correctly attached to spindle microtubules before the cell progresses into anaphase. This checkpoint monitors the tension status of each kinetochore and blocks the initiation of anaphase if any kinetochores lack proper attachment.
5. **Microtubule dynamics:** Once the SAC is satisfied, the cell enters anaphase, and the spindle microtubules undergo depolymerization, pulling the sister chromatids apart. This separation process is tightly regulated by factors that promote microtubule depolymerization and kinetochore disassembly.
The positive regulation of attachment of spindle microtubules to kinetochore involves the coordinated action of many different proteins and pathways. Disruptions in this process can lead to aneuploidy, a condition where cells have an abnormal number of chromosomes, which is often associated with cancer and other diseases.'
