Spindle assembly checkpoint activation and silencing at kinetochores. [PDF]
The spindle assembly checkpoint (SAC) is a surveillance mechanism that promotes accurate chromosome segregation in mitosis. The checkpoint senses the attachment state of kinetochores, the proteinaceous structures that assemble onto chromosomes in mitosis in order to mediate their interaction with spindle microtubules.

Reverse engineering of the spindle assembly checkpoint. [PDF]
The Spindle Assembly Checkpoint (SAC) is an intracellular mechanism that ensures proper chromosome segregation. By inhibiting Cdc20, a co-factor of the Anaphase Promoting Complex (APC), the checkpoint arrests the cell cycle until all chromosomes are ...

Deficient spindle assembly checkpoint in multiple myeloma.
Multiple myeloma (MM) is a hematological disease characterized by an abnormal accumulation of plasma cells in the bone marrow. These cells have frequent cytogenetic abnormalities including translocations of the immunoglobulin heavy chain gene and ...

In-silico modeling of the mitotic spindle assembly checkpoint. [PDF]
The Mitotic Spindle Assembly Checkpoint ((M)SAC) is an evolutionary conserved mechanism that ensures the correct segregation of chromosomes by restraining cell cycle progression from entering anaphase until all chromosomes have made proper bipolar ...

Cell rounding at mitosis is driven by cortical tension and maintained through metaphase, although the mechanism is unknown. Here, the authors demonstrate that Cdk1 phosphorylation of DIAPH1 is required for both cortical tension maintenance and ...

A Cell Biological Perspective on Past, Present and Future Investigations of the Spindle Assembly Checkpoint [PDF]
The spindle assembly checkpoint (SAC) is a quality control mechanism that ensures accurate chromosome segregation during cell division. It consists of a mechanochemical signal transduction mechanism that senses the attachment of chromosomes to the ...

Summary: Faithful chromosome segregation during mitosis depends on the spindle assembly checkpoint (SAC), which delays progression through mitosis until every chromosome has stably attached to spindle microtubules via the kinetochore.

Mitotic spindle disruption in human preimplantation embryos activates the spindle assembly checkpoint but not apoptosis until Day 5 of development [PDF]
STUDY QUESTION Is the spindle assembly checkpoint (SAC) active during human preimplantation development? SUMMARY ANSWER Mitotic spindle disruption during mitosis activates the SAC from at least Day 3 of human preimplantation development, but this does ...
