The Rad50S allele promotes ATM-dependent DNA damage responses and suppresses ATM deficiency: implications for the Mre11 complex as a DNA damage sensor (2005)

Morales, Monica, Theunissen, Jan-Willem F., Kim, Carla F. Bender, Kitagawa, Risa, Kastan, Michael B., Petrini, John H.J.

Genetic and cytologic data from Saccharomyces cerevisiae and mammals implicate the Mre11 complex, consisting of Mre11, Rad50, and Nbs1, as a sensor of DNA damage, and indicate that the complex...

Phosphorylation of SMC1 is a critical downstream event in the ATM-NBS1-BRCA1 pathway (2004)

Kitagawa, Risa, Bakkenist, Christopher J., McKinnon, Peter J., Kastan, Michael B.

The ATM protein kinase is activated by intermolecular autophosphorylation in response to DNA damage and initiates cellular signaling pathways that facilitate cell survival and reduce chromosomal...

EMB-30: An APC4 Homologue Required for Metaphase-to-Anaphase Transitions during Meiosis and Mitosis in Caenorhabditis elegans

Furuta, Tokiko, Tuck, Simon, Kirchner, Jay, Koch, Bryan, Auty, Roy, Kitagawa, Risa, ...

Here we show that emb-30 is required for metaphase-to-anaphase transitions during meiosis and mitosis in Caenorhabditis elegans. Germline-specific emb-30 mutant alleles block the meiotic divisions....

Negative control of replication initiation by a novel chromosomal locus exhibiting exceptional affinity for Escherichia coli DnaA protein

Kitagawa, Risa, Ozaki, Toru, Moriya, Shigeki, Ogawa, Tohru

Replication of the Escherichia coli chromosome is initiated at a unique site, oriC. Concurrent initiation occurs at all oriC sites present in a cell once, and only once, per cell cycle. A mechanism...

Suppressors of Spindle Checkpoint Defect (such) Mutants Identify New mdf-1/MAD1 Interactors in Caenorhabditis elegans

Tarailo, Maja, Kitagawa, Risa, Rose, Ann M.

The spindle assembly checkpoint (SAC) governs the timing of metaphase-to-anaphase transition and is essential for genome stability. The Caenorhabditis elegans mutant strain gk2 carries a deletion...

Spatial organization of the mammalian genome surveillance machinery in response to DNA strand breaks

Bekker-Jensen, Simon, Lukas, Claudia, Kitagawa, Risa, Melander, Fredrik, Kastan, Michael B., Bartek, Jiri, ...

We show that DNA double-strand breaks (DSBs) induce complex subcompartmentalization of genome surveillance regulators. Chromatin marked by γ-H2AX is occupied by ataxia telangiectasia–mutated (ATM)...

Spindle assembly checkpoint gene mdf-1 regulates germ cell proliferation in response to nutrition signals in C. elegans

Watanabe, Sonoko, Yamamoto, Takaharu G, Kitagawa, Risa

When newly hatched Caenorhabditis elegans larvae are starved, their primordial germ cells (PGCs) arrest in the post-S phase. This starvation-induced PGC arrest is mediated by the...

SPDL-1 functions as a kinetochore receptor for MDF-1 in Caenorhabditis elegans

Yamamoto, Takaharu G., Watanabe, Sonoko, Essex, Anthony, Kitagawa, Risa

The spindle assembly checkpoint (SAC) ensures faithful chromosome segregation by delaying anaphase onset until all sister kinetochores are attached to bipolar spindles. An RNA interference screen for...
