A cDNA encodes p107; a cell contains recombinant p107-encoding DNA; and substantially all of the cells of a nonhuman mammal contain recombinant p107-encoding DNA. Also, a method for diagnosing a condition of tumorigenicity in a subject, includes the steps of obtaining a tissue sample from the subject and detecting the presence of non wild-type p107-encoding gene in the sample, or detecting the absence of wild-type p107-encoding gene in the sample; or extracting DNA from the sample and detecting the presence of non wild-type p107-encoding gene or the absence of wild-type p107-encoding gene in the DNA. Also, a nucleic acid probe is complementary to a portion of a human mutant p107 gene.

DNA encoding p107 tumor suppressor and related polypeptides

The invention features an isolated nucleic acid hybridizable with the complement of the coding strand nucleic acid sequence presented in SEQ ID NO:1, and encoding a protein that is necessary for adenovirus transformation of a mammalian cell. The encoded protein, p300, cooperates with adenovirus E1A (Early-region 1A) proteins to establish the transformed state.
