The END network couples spindle pole assembly to inhibition of the anaphase - promoting complex / cyclosome in early mitosis.

Martin Schwickart (Zachariae, MPG)-- «Molecular analysis of novel subunits of the anaphase - promoting complex (APC / C) in yeast» (2005)

Plk1 regulates activation of the anaphase promoting complex by phosphorylating and triggering SCFβTrCP - dependent destruction of the APC inhibitor Emi1.

In approximately 43 % of the dividing human cells Kiyomitsu observed, the middle of the mitotic spindle was properly centered at the beginning of anaphase.

The close temporal association of the [Ca2 +] i transient with the onset of anaphase suggests that calcium may have a signaling role in this event.

Not exact matches

In the majority of cells arrested after S phase but before anaphase, sister minichromosome molecules are not topologically interlocked with each other.

The role of DNA topology in holding sister chromatids together before anaphase was investigated by analyzing the structure of a small circular minichromosome in cell cycle (cdc) mutants of the yeast Saccharomyces cerevisiae.

However, mitotic cells showed a rapid elevation of [Ca2 +] i from basal levels of 130 nM to 500 to 800 nM at the metaphase - anaphase transition.

Prior studies by Kerr el al, showed that PP2ACdc55 played an essential role in controlling the timing of metaphase to anaphase during meiosis, in other words preventing cells from prematurely exiting meiosis.

Despite this hard work from dynein, in roughly one - quarter of the cells observed, the spindle was misaligned, even after the paired chromosomes were pulled to opposite sides of the cell in late anaphase.

Kiyomitsu's latest work focuses on the next step of mitosis, called anaphase, when the microtubules tear the paired chromosomes apart so that one copy of each chromosome ends up in each of the new daughter cells.

In telomeric DNA mutants of Tetrahymena thermophila, created by expression of a telomerase RNA with an altered template sequence, division of the germline nucleus was severely delayed or blocked in anaphase.

As seen in this merged fluorescent image (early anaphase marked with magenta; late anaphase marked with green), such cells correct this problem by adjusting their cell membranes relative to the spindle (right), instead of shifting their spindles within the cell.

Zuzana Markova (Zachariae, MPG)-- «Regulation of Meiotic Prophase by the Anaphase - Promoting Complex» (2012)

Such perfect division depends on the position of the mitotic spindle (chromosomes, microtubules, and spindle poles) within the cell, and it's now clear that human cells employ two specific mechanisms during the portion of division known as anaphase to correct mitotic spindle positioning.

This not only ensures that sister chromatids remain cohesed until the metaphase - to - anaphase transition, but also provides us with the stereotypical image of an X-shaped chromosome.
