Description:
GADD45 is a ubiquitously expressed mammalian gene that is induced by DNA damage and certain other stresses. Like another p53-regulated gene, p21WAF1/CIP1, whose product binds to cyclin-dependent kinases (Cdk's) and proliferating cell nuclear antigen (PCNA), GADD45 has been associated with growth suppression. Gadd45 was found to bind to PCNA, a normal component of Cdk complexes and a protein involved in DNA replication and repair. Gadd45 stimulated DNA excision repair in vitro and inhibited entry of cells into S phase. These results establish GADD45 as a link between the p53-dependent cell cycle checkpoint and DNA repair.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Smith, M L -- Chen, I T -- Zhan, Q -- Bae, I -- Chen, C Y -- Gilmer, T M -- Kastan, M B -- O'Connor, P M -- Fornace, A J Jr -- ES05777/ES/NIEHS NIH HHS/ -- New York, N.Y. -- Science. 1994 Nov 25;266(5189):1376-80.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Molecular Pharmacology, National Cancer Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7973727" target="_blank"〉PubMed〈/a〉
