Summary
NIMA-related kinases (Neks) are crucial for cell division, regulating mitosis and chromosome stability. Dysregulation of these kinases may offer new targets for cancer chemotherapy.
Area of Science:
- Cell Biology
- Molecular Biology
- Biochemistry
Background:
- NIMA-related kinases (Neks) are serine/threonine kinases involved in cell cycle control.
- Neks regulate key mitotic events like entry into mitosis, chromatin condensation, spindle organization, and cytokinesis.
- Mammalian cells have eleven Neks (Nek1-Nek11), with Nek2, Nek6, Nek7, and Nek9 known to regulate mitosis.
Purpose of the Study:
- To review the role of NIMA-related kinases in mitotic progression.
- To highlight the functions of Neks in microtubule organization and spindle assembly.
- To discuss the potential of Neks as chemotherapeutic targets.
Main Methods:
- Literature review of studies on NIMA-related kinases.
- Analysis of functional roles in cell cycle control and mitosis.
- Examination of subcellular localization, particularly at microtubule organizing centers.
Main Results:
- Neks are essential for orchestrating mitotic progression across species.
- Several Neks localize to centrosomes/spindle pole bodies, regulating microtubule organization and spindle assembly.
- Neks also play roles in non-dividing cells, regulating cilia and flagella.
Conclusions:
- NIMA-related kinases are significant contributors to mitotic progression and genomic stability.
- These kinases are promising targets for novel cancer chemotherapeutics.

02:15M-Cdk Drives Transition Into Mitosis
Checkpoints throughout the cell cycle serve as safeguards and gatekeepers, allowing the cell cycle to progress in favorable conditions and slow or halt it in problematic ones. This regulation is known as the cell cycle control system.
Cyclin-dependent kinases, or Cdks, work in concert with cyclins to control cell cycle transitions. M-Cdk, a complex of Cdk1 bound to M cyclin, is a well-known example of this coordinated control that drives the transition from the G2 to the M phase.

02:39Positive Regulator Molecules
Mitotic cell division results in daughter cells that exactly resemble the parent cell. However, errors in the DNA replication or distribution of genetic material may lead to genetic mutations that may be passed down to every new cell formed from the resulting abnormal cell. Propagation of such mutant cells is restricted through checkpoint mechanisms present at different stages of the cell cycle. These checkpoints involve regulator molecules that either promote or demote cell cycle events.

To consistently produce healthy cells, the cell cycle—the process that generates daughter cells—must be precisely regulated.
02:34Inhibition of Cdk Activity
The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
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...
