Rb, whi it's not just for metazoans anymoreK Cooper
Department of Molecular Biology, UMDNJ SOM, Stratford, NJ 08084, USA
Oncogene 25:5228-32. 2006..This review will discuss the difference and similarities between how these proteins play similar roles in controlling G1 progression...
Meiotic control of the APC/C: similarities & differences from mitosisKatrina F Cooper
University of Medicine and Dentistry of New Jersey, 2 Medical Center Drive, Stratford, NJ 08055, USA
Cell Div 6:16. 2011..In Saccharomyces cerevisiae, this meiosis-specific activator is called Ama1. This review summarizes our knowledge of how Cdc20 and Ama1 coordinate APC/C activity to regulate the meiotic nuclear divisions in yeast...- Pds1p is required for meiotic recombination and prophase I progression in Saccharomyces cerevisiaeKatrina F Cooper
Department of Biochemistry, Drexel University College of Medicine, Philadelphia, PA 19102, USA
Genetics 181:65-79. 2009..This role is meiosis specific as Mcd1p destruction is not altered in vegetative pds1Delta cultures. These results define a previously undescribed role for Pds1p in cohesin maintenance, recombination, and meiotic progression... - Meiosis-specific destruction of the Ume6p repressor by the Cdc20-directed APC/CMichael J Mallory
Institute for Cancer Research, Fox Chase Cancer Center, Philadelphia, PA 19111, USA
Mol Cell 27:951-61. 2007..These findings demonstrate a direct connection between the transcription machinery and ubiquitin-mediated proteolysis that is developmentally regulated... - Cyclin B-cdk activity stimulates meiotic rereplication in budding yeastRandy Strich
Institute for Cancer Research, Fox Chase Cancer Center, Philadelphia, Pennsylvania 19111, USA
Genetics 167:1621-8. 2004..Moreover, the production of haploids, regardless of the genome content, suggests that the cell counts replication cycles, not chromosomes, in determining the number of nuclear divisions to execute... - Regulation of the oxidative stress response through Slt2p-dependent destruction of cyclin C in Saccharomyces cerevisiaeElizabeth Krasley
Institute for Cancer Research, Fox Chase Cancer Center, Philadelphia, Pennsylvania 19111, USA
Genetics 172:1477-86. 2006..These findings demonstrate a new role for the Slt2p MAP kinase cascade in protecting the cell from programmed cell death through cyclin C destruction... - Ama1p-activated anaphase-promoting complex regulates the destruction of Cdc20p during meiosis IIGrace S Tan
Department of Biochemistry and Molecular Biology, Drexel Medical School, Philadelphia, PA 19102, USA
Mol Biol Cell 22:315-26. 2011..These findings provide a mechanism to temporally down-regulate APC/C(Cdc20) activity as the cells complete meiosis II and form spores... - The Ama1-directed anaphase-promoting complex regulates the Smk1 mitogen-activated protein kinase during meiosis in yeastChristine M McDonald
Department of Biochemistry and Molecular Biology, Drexel University College of Medicine, Philadelphia, Pennsylvania 19102, USA
Genetics 171:901-11. 2005..We propose that this novel mechanism for controlling MAPK activation plays a role in coupling the completion of meiosis II to gamete formation... - Oxidative-stress-induced nuclear to cytoplasmic relocalization is required for Not4-dependent cyclin C destructionKatrina F Cooper
Department of Molecular Biology, University of Medicine and Dentistry New Jersey, Two Medical Center Drive, Stratford, NJ 08055, USA
J Cell Sci 125:1015-26. 2012..These results identify a stress-induced proteolytic pathway regulating cyclin C that requires nuclear to cytoplasmic relocalization and Not4p-mediated ubiquitylation... - Saccharomyces cerevisiae C-type cyclin Ume3p/Srb11p is required for efficient induction and execution of meiotic developmentKatrina F Cooper
Program for Cell and Developmental Biology, Fox Chase Cancer Center, Philadelphia, Pennsylvania 19111, USA
Eukaryot Cell 1:66-74. 2002..In conclusion, these findings indicate that Srb11p is required for both entry into and execution of the meiotic program, thus describing multiple roles for a C-type cyclin in the regulation of a developmental pathway...
