Ataxia telangiectasia-mutated phosphorylates Chk2 in vivo and in vitro

Matsuoka, Shuhei, Rotman, Galit, Ogawa, Akira, Shiloh, Yosef, Tamai, Katsuyuki, Elledge, Stephen J.

The protein kinase Chk2, the mammalian homolog of the budding yeast Rad53 and fission yeast Cds1 checkpoint kinases, is phosphorylated and activated in response to DNA damage by ionizing radiation...

Requirement of ATM in Phosphorylation of the Human p53 Protein at Serine 15 following DNA Double-Strand Breaks

Nakagawa, Kazumi, Taya, Yoichi, Tamai, Katsuyuki, Yamaizumi, Masaru

Microinjection of the restriction endonuclease HaeIII, which causes DNA double-strand breaks with blunt ends, induces nuclear accumulation of p53 protein in normal and xeroderma pigmentosum (XP)...

The Second-Largest Subunit of the Mouse DNA Polymerase α-Primase Complex Facilitates Both Production and Nuclear Translocation of the Catalytic Subunit of DNA Polymerase α

Mizuno, Takeshi, Ito, Nobutoshi, Yokoi, Masayuki, Kobayashi, Akio, Tamai, Katsuyuki, Miyazawa, Hiroshi, ...

DNA polymerase α-primase is a replication enzyme necessary for DNA replication in all eukaryotes examined so far. Mouse DNA polymerase α is made up of four subunits, the largest of which is the...

The human homologs of checkpoint kinases Chk1 and Cds1 (Chk2) phosphorylate p53 at multiple DNA damage-inducible sites

Shieh, Sheau-Yann, Ahn, Jinwoo, Tamai, Katsuyuki, Taya, Yoichi, Prives, Carol

Upon DNA damage, the amino terminus of p53 is phosphorylated at a number of serine residues including S20, a site that is particularly important in regulating stability and function of the protein....

Chk1 is an essential kinase that is regulated by Atr and required for the G2/M DNA damage checkpoint

Liu, Qinghua, Guntuku, Saritha, Cui, Xian-Shu, Matsuoka, Shuhei, Cortez, David, Tamai, Katsuyuki, ...

Chk1, an evolutionarily conserved protein kinase, has been implicated in cell cycle checkpoint control in lower eukaryotes. By gene disruption, we show that CHK1 deficiency results in a severe...

Multiple Ras-dependent phosphorylation pathways regulate Myc protein stability

Sears, Rosalie, Nuckolls, Faison, Haura, Eric, Taya, Yoichi, Tamai, Katsuyuki, Nevins, Joseph R.

Our recent work has shown that activation of the Ras/Raf/ERK pathway extends the half-life of the Myc protein and thus enhances the accumulation of Myc activity. We have extended these observations...

Regulation of checkpoint kinases through dynamic interaction with Crb2

Mochida, Satoru, Esashi, Fumiko, Aono, Nobuki, Tamai, Katsuyuki, O'Connell, Matthew J, Yanagida, Mitsuhiro

ATR/Rad3-like kinases promote the DNA damage checkpoint through regulating Chk1 that restrains the activation of cyclin-dependent kinases. In fission yeast, Crb2, a BRCT-domain protein that is...

Isolation and characterization of the TIGA genes, whose transcripts are induced by growth arrest

Yabuta, Norikazu, Onda, Hiroaki, Watanabe, Masafumi, Yoshioka, Naohisa, Nagamori, Ippei, Funatsu, Tomoyuki, ...

We report here the isolation of 44 genes that are upregulated after serum starvation and/or contact inhibition. These genes have been termed TIGA, after Transcript Induced by Growth Arrest. We found...
