Meiosis in budding yeast

GV Börner, A Hochwagen, AJ MacQueen - Genetics, 2023 - academic.oup.com
Meiosis is a specialized cell division program that is essential for sexual reproduction. The
two meiotic divisions reduce chromosome number by half, typically generating haploid …

Shugoshins: tension-sensitive pericentromeric adaptors safeguarding chromosome segregation

AL Marston - Molecular and cellular biology, 2015 - Am Soc Microbiol
The shugoshin/Mei-S332 family are proteins that associate with the chromosomal region

Rewiring of the phosphoproteome executes two meiotic divisions in budding yeast

LB Koch, C Spanos, V Kelly, T Ly, AL Marston - The EMBO journal, 2024 - embopress.org

gametes via meiosis, two distinct and sequential chromosome segregation events occur …

Chromosome segregation in budding yeast: sister chromatid cohesion and related mechanisms

AL Marston - Genetics, 2014 - academic.oup.com
Studies on budding yeast have exposed the highly conserved mechanisms by which
duplicated chromosomes are evenly distributed to daughter cells at the metaphase …

Mitotic phosphatases: from entry guards to exit guides

M Bollen, DW Gerlich, B Lesage - Trends in cell biology, 2009 - cell.com
While the importance of protein kinases for the spatial and temporal control of mitotic events

Securin-independent regulation of separase by checkpoint-induced shugoshin–MAD2

S Hellmuth, L Gómez-H, AM Pendás, O Stemmann - Nature, 2020 - nature.com

Shugoshin biases chromosomes for biorientation through condensin recruitment to the pericentromere

KF Verzijlbergen, OO Nerusheva, D Kelly, A Kerr… - Elife, 2014 - elifesciences.org
To protect against aneuploidy, chromosomes must attach to microtubules from opposite
poles ('biorientation') prior to their segregation during mitosis. Biorientation relies on the …

Establishment of cohesion at the pericentromere by the Ctf19 kinetochore subcomplex and the replication fork-associated factor, Csm3

J Fernius, AL Marston - PLoS genetics, 2009 - journals.plos.org
The cohesin complex holds sister chromatids together from the time of their duplication in S
