The importance of p53 in carcinogenesis stems from its central role in inducing cell cycle arrest or apoptosis in response to cellular stresses. We have identified a Drosophila homolog of p53 ("Dmp53"). Like mammalian p53, Dmp53 binds specifically to human p53 binding sites, and overexpression of Dmp53 induces apoptosis. Importantly, inhibition of Dmp53(More)
DNA fragments that show retarded electrophoretic mobility through polyacrylamide gels have been found in both prokaryotes and eukaryotes. In the case of kinetoplast DNA, evidence has been presented that the DNA is curved or 'bent'. Bent DNA has previously been found at the lambda and simian virus 40 (SV40) DNA replication origins. Here we show the existence(More)
