Abstract
AbstractOf the many genes mutated on the road to tumor formation, few have received as much attention as p53. The gene has come to occupy center stage for the simple reason that it is more frequently altered in human tumors than any other known gene, undergoing mutation at a significant rate in almost every tumor type in which it has been studied. This association between p53 mutation and tumorigenesis has spurred a flurry of research attempting to delineate the normal function of p53 and, by extension, the role of p53 mutation in tumor formation. At the cellular level, p53 has been shown to suppress growth. Recent efforts to further discern the function of p53 have centered on the underlying molecular basis for this growth suppression. In particular, research has focused on the identification of cellular molecules (specifically DNA and proteins) with which the p53 protein associates. p53 has now been shown to bind DNA in a sequence‐specific manner, and mounting evidence suggests that p53 acts as a transcription factor, perhaps regulating the expression levels of genes involved in the inhibition of cell growth. The logical next step in understanding p53 function involves the resolution of two questions: (1) what are the physiological transcriptional targets of p53, and (2) what cellular proteins regulate or mediate the ability of p53 to modulate transcription? Some initial clues to these puzzles are now emerging, and these form the subject of this review.
