Chromokinesins
WebJul 1, 2005 · The chromokinesins are a subgroup of kinesin motors. Chromokinesins act in various steps of mitosis, including chromosome condensation, metaphase alignment, chromosome segregation, cytokinesis and they help maintain genome stability. WebYou’ve just successfully performed chronokinesis. Mind The Gap Instead of focusing on the ticks and tocks, this technique focuses on the quiet space in between them.

WebMar 3, 2003 · The motile activity, directionality and processivity of all chromosome arm chromokinesins except for nod and Kid are still unknown. The examination of motility of all chromokinesins in vitro will help us to understand the molecular mechanism of the chromosome movement in mitosis in vivo. Materials and methods WebChromokinesins, a family of chromosome-associated microtubule motors, are potential generators of aneuploidy since they are believed to participate in spindle morphogenesis and chromosome movements during mitosis. Our hypothesis is that inhibition of chromokinesin activity increases the aneuploid frequency in cultured cells. Five different ...
WebSep 21, 2011 · The bipolar spindle is a highly dynamic structure that assembles transiently around the chromosomes and provides the mechanical support and the forces required for chromosome segregation. Spindle assembly and chromosome movements rely on the regulation of microtubule dynamics and a fine balance of forces exerted by various … WebMay 15, 2012 · This mechanism, which operates independently of chromokinesins and interkinetochore tension, is the primary way human cells prevent chromosomes from straying too far from the spindle midzone ( Figure 6F ). Kid and Kif4A also contribute to the spatial control of centromere movements.
WebRegarding the function of kinetochore motors that influence chromosome congression movement, perturbation of CENP-E and chromokinesins can influence the maintenance of alignment of chromosomes at the equator [19,51,52,53], but it is not clear if this is related to the same mechanical causes as during congression. 4. Biomechanical and Molecular ... WebSep 3, 2012 · Chromokinesins are microtubule plus end–directed motor proteins that bind to chromosome arms. In Xenopus egg cell-free extracts, Xkid and Xklp1 are essential for bipolar spindle formation but the...

Left: Schematics of the rationale of our kinesin-based chromosome mis-segregation approach. Chromosome congression toward the spindle equator is facilitated by KT-MT attachments and plus-end-directed microtubule-based motors, such as chromokinesins at chromosome arms, and CENP-E at kinetochores (KTs). norlys mit loginWebJul 1, 2005 · Chromokinesins are clearly crucial components of the mitotic machinery and are required for accurate genome segregation. Not surprisingly, loss of chromokinesin function leads to deleterious genome defects, particularly an increased number of anaphase bridges and micronuclei. how to remove new tab ads
