Abstract:
:The adenovirus type 5 (Ad5) 55-kDa E1B oncoprotein has been shown to form complexes with the p53 tumor suppressor protein. These complexes are thought to interfere with normal p53 activity and may be responsible for the paucity of p53 mutations in cells transformed by these viruses. This report describes an example of a p53 mutation in exon 5 in an Ad5-transformed cell line that exhibited less expression of E1B 55-kDa protein and a longer tumor-latency phenotype than another Ad5-transformed cell line expressing wild-type p53. The finding of a p53 mutation in an Ad5-transformed cell line is unusual, especially considering the current theory that p53-E1B interactions play an important role in adenovirus transformation. This mutation could represent an alternative method of inactivating p53 function in the absence of sufficient levels of E1B 55-kDa oncoprotein.
