General description

Mitotic arrest deficient-like 1 (yeast) is also known as MAD1 and MAD1L1. It is part of the MAD1 family which is crucial to development. MAD1 acts as a checkpoint during mitotic spindle assembly. During anaphase and telophase MAD1 is located at the spindle mid-zone of the cell, where it prevents anaphase until the chromosome is aligned at the metaphase plate. During metaphase MAD1 is located at the centrosome. MAD1 participates in cell cycle control and tumor suppression. MAD1 functions as a homodimer and interacts with MAD2L1. It is thought that MAD1 recruits to MAD2, which then promotes binding of MAD2 to CDC20.

Immunogen

His-tagged recombinant protein corresponding to human Mad1.

Kinetochores are proteinaceous scaffolds implicated in the formation of load-bearing attachments of chromosomes to microtubules during mitosis. Kinetochores contain distinct chromatin- and microtubule-binding interfaces, generally defined as the inner and outer kinetochore, respectively (reviewed in). The constitutive centromere-associated network (CCAN)

Through exome sequencing, we identified six individuals with biallelic loss-of-function mutations in TRIP13. All six developed Wilms tumor.

Fidelity of chromosome segregation is ensured by a tension-dependent error correction system that prevents stabilization of incorrect chromosome-microtubule attachments. Unattached or incorrectly attached chromosomes also activate the spindle assembly checkpoint, thus delaying mitotic exit until all chromosomes are bioriented. The

Mitotic kinetochores are signaling network hubs that regulate chromosome movements, attachment error-correction, and the spindle assembly checkpoint. Key switches in these networks are kinases and phosphatases that enable rapid responses to changing conditions. Describing the mechanisms and dynamics of their
