Intertwined Functions of Separase and Caspase in Cell Division and Programmed Cell Death. [PDF]
, 2020 Timely sister chromatid separation, promoted by separase, is essential for faithful chromosome segregation. Separase is a member of the CD clan of cysteine proteases, which also includes the pro-apoptotic enzymes known as caspases.

Massive gene amplification on a recently formed Drosophila Y chromosome. [PDF]
, 2019 Widespread loss of genes on the Y is considered a hallmark of sex chromosome differentiation. Here we show that the initial stages of Y evolution are driven by massive amplification of distinct classes of genes. The neo-Y chromosome of Drosophila miranda

Chromosome Segregation: Monopolin Goes Spindle [PDF]
Current Biology, 2009 At anaphase onset the mitotic spindle undergoes dramatic changes in order to segregate sister chromatids. Surprisingly, the monopolin complex, best known for its role at kinetochores in meiosis, is now shown to localize to, and stabilize, the mitotic anaphase spindle.

Advanced Science, EarlyView.In this article, Shuai and colleagues found that depletion of Sorcs3 could activate totipotency in mESCs, promising bidirectional differentiation potential to embryonic and extraembryonic lineages. The underlying mechanism might be activation of Tfap2c and repression of TGF‐β, PI3K‐AKT, and lysosome pathways.

mBio, 2019 Coordinating chromosome duplication and segregation with cell division is clearly critical for bacterial species with one chromosome. The precise choreography required is even more complex in species with more than one chromosome.

How to halve ploidy : lessons from budding yeast meiosis [PDF]
, 2012 Maintenance of ploidy in sexually reproducing organisms requires a specialized form of cell division called meiosis that generates genetically diverse haploid gametes from diploid germ cells.

Chromosome Segregation: Reconstituting the Kinetochore [PDF]
Current Biology, 2016 Faithful chromosome segregation is accomplished by attachment of chromosomes to spindle microtubules using the kinetochore. In a major step forward in understanding the functional and structural complexity of kinetochores, a 21-subunit human centromere - kinetochore complex has been reconstituted entirely from purified components, recreating the ...

p53 Prohibits Propagation of Chromosome Segregation Errors that Produce Structural Aneuploidies
Cell Reports, 2017 Summary: The presence of an abnormal karyotype has been shown to be profoundly detrimental at the cellular and organismal levels but is an overt hallmark of cancer.

MatP regulates the coordinated action of topoisomerase IV and MukBEF in chromosome segregation
Nature Communications, 2016 The Escherichia coli SMC complex, MukBEF, forms clusters of molecules that interact with the decatenase topisomerase IV and which are normally associated with the chromosome replication origin region (ori).
