Kinetochore Fiber Maturation in PtK
Kinetochore microtubules (kMts) are a subset of spindle microtubules that bind directly to the kinetochore to form the kinetochore fiber (K-fiber). The K-fiber in turn interacts with the kinetochore to produce chromosome motion toward the attached spindle pole. We have examined K-fiber maturation in PtK 1 cells using same-cell video light microscopy/serial section EM. During congression, the ki...
متن کاملKinetochore microtubules in PTK cells
We have analyzed the fine structure of 10 chromosomal fibers from mitotic spindles of PtK1 cells in metaphase and anaphase, using electron microscopy of serial thin sections and computer image processing to follow the trajectories of the component microtubules (MTs) in three dimensions. Most of the kinetochore MTs ran from their kinetochore to the vicinity of the pole, retaining a clustered arr...
متن کاملKinetochore structure: electron spectroscopic imaging of the kinetochore
The structure of the kinetochore in thin section has been studied in the Indian muntjac by an electron spectroscopic imaging technique. This procedures allows the analysis of the distribution of phosphorus within the layers of the kinetochore. The results indicate that this element is a major component of both the inner and outer plates whereas it is largely absent in the middle plate and fibro...
متن کاملTension Management in the Kinetochore
The kinetochore is the protein machine built at the centromere that integrates mechanical force and chemical energy from dynamic microtubules into directed chromosome motion. The kinetochore also provides a powerful signaling function that is able to alter the properties of the spindle checkpoint and initiate a signal transduction cascade that leads to inhibition of the anaphase promoting compl...
