Three-dimensional ultrastructural analysis of yeast mitotic spindle microtubules has been accomplished by reconstruction from serial thin sections of cells (Winey et al. 1995) and by electron tomography of thick sections of cells (O’Toole et al. 1999) (Figure 1).The work confirmed that kinetochores are attached by a single microtubule as suggested in early high-voltage Mitotic spindle function in Saccharomyces cerevisiae requires a balance between different types of kinesin-related motors.

(2010). Mitotic spindles are microtubule-based structures responsible for chromosome partitioning during cell division. Although the roles of microtubules and microtubule-based motors in mitotic spindles are well established, whether or not actin filaments (F-actin) and F-actin–based motors (myosins) are required components of mitotic spindles has long been controversial. Gulluni et al. reveal a kinase-independent scaffolding function of PI3K-C2α that affects mitotic spindle formation. Reduced levels of PI3K-C2α reduce tumor growth initially but provide a growth advantage later in mouse models of breast cancer.

However, accumulated discoveries indicate that chromosomes play a key role Mitotic Spindle: Definition, Formation & Function Chapter 12 / Lesson 6 Transcript Video Quiz & Worksheet - The Mitotic Spindle Quiz Course The mitotic spindle is a structure of the eukaryotic cytoskeleton involved in mitosis and meiosis. Conversely, the molecular mechanisms regulating mitotic spindle function have been much more challenging to decipher for several reasons: 1. it is extremely large and complex, often comprised of hundreds to thousands of microtubules, 2. it is one of the most dynamic cytoskeletal structures, and 3. there are a multitude of microtubule associated proteins (MAPs) that participate in the formation Required for the execution of the mitotic checkpoint which monitors the process of kinetochore-spindle attachment and delays the onset of anaphase when this process is not complete. It inhibits the activity of the anaphase promoting complex by sequestering CDC20 until all chromosomes are aligned at the metaphase plate. Mitotic Spindle Integrity and Kinetochore Function Linked by the Duo1p/Dam1p Complex Iain M. Cheeseman, Maria Enquist-Newman, Thomas Müller-Reichert, David G. Drubin, Although the spindle localization is consistent with a mitotic function, the concentration of the protein at spindle poles rather than at regions of microtubule overlap is somewhat unexpected.

Correct assembly and function of the mitotic spindle during cell division is essential for the accurate partitioning of the duplicated genome to daughter cells. Protein phosphorylation has long been implicated in controlling spindle function and chromosome segregation, and genetic studies have identified several protein kinases and phosphatases that are likely to regulate these processes. Thorough and informative, The Mitotic Spindle: Methods and Protocols, is a valuable resource for researchers who are new to mitosis or are already experts in the field.

The Saccharomyces cerevisiae mitotic spindle in budding yeast is exemplified by its simplicity and elegance. Microtubules are nucleated from a crystalline array of proteins organized in the nuclear envelope, known as the spindle pole body in yeast (analogous to the centrosome in larger eukaryotes).
