Kinetochore-generated pushing forces separate centrosomes during bipolar spindle assembly [PDF]
In animal somatic cells, bipolar spindle formation requires separation of the centrosome-based spindle poles. Centrosome separation relies on multiple pathways, including cortical forces and antiparallel microtubule (MT) sliding, which are two activities

In many eukaryotes, the centromere is epigenetically specified and not strictly defined by sequence. In contrast, budding yeast has a specific 125 bp sequence required for kinetochore function.

The ultrastructure of the kinetochore and kinetochore fiber in Drosophila somatic cells [PDF]
Drosophila melanogaster is a widely used model organism for the molecular dissection of mitosis in animals. However, despite the popularity of this system, no studies have been published on the ultrastructure of Drosophila kinetochores and kinetochore fibers (K-fibers) in somatic cells.

Checkpoint proteins come under scrutiny [PDF]
Details are emerging of the interactions between the kinetochore and various spindle checkpoint proteins that ensure that sister chromatids are equally divided between daughter cells during cell ...

Mitotic control of kinetochore-associated dynein and spindle orientation by human Spindly [PDF]
Mitotic spindle formation and chromosome segregation depend critically on kinetochore-microtubule (KT-MT) interactions. A new protein, termed Spindly in Drosophila and SPDL-1 in C.

Kinetochore-microtubule error correction is driven by differentially regulated interaction modes [PDF]
For proper chromosome segregation, sister kinetochores must interact with microtubules from opposite spindle poles (bi-orientation). To establish bi-orientation, aberrant kinetochore-microtubule attachments are disrupted (error correction) by aurora B ...

The RZZ complex requires the N-terminus of KNL1 to mediate optimal Mad1 kinetochore localization in human cells [PDF]
The spindle assembly checkpoint is a surveillance mechanism that blocks anaphase onset until all chromosomes are properly attached to microtubules of the mitotic spindle.

Synergistic Control of Kinetochore Protein Levels by Psh1 and Ubr2.
The accurate segregation of chromosomes during cell division is achieved by attachment of chromosomes to the mitotic spindle via the kinetochore, a large multi-protein complex that assembles on centromeres.

The kinetochore, a multi-protein complex assembled on centromeres, is essential to segregate chromosomes during cell division. Deficiencies in kinetochore function can lead to chromosomal instability and aneuploidy-a hallmark of cancer cells. Kinetochore

Monopolin subunit Csm1 associates with MIND complex to establish monopolar attachment of sister kinetochores at meiosis I [PDF]
Sexually reproducing organisms halve their cellular ploidy during gametogenesis by undergoing a specialized form of cell division known as meiosis. During meiosis, a single round of DNA replication is followed by two rounds of nuclear divisions (referred
