Deciphering the acetylation code of p53 in transcription regulation and tumor suppression.

ABSTRACT: Although it is well-established that p53-mediated tumor suppression mainly acts through its ability in transcriptional regulation, the molecular mechanisms of this regulation are not completely understood. Among a number of regulatory modes, acetylation of p53 attracts great interests. p53 was one of the first non-histone proteins found to be functionally regulated by acetylation and deacetylation, and subsequent work has established that reversible acetylation is a general mechanism for regulation of non-histone proteins. Unlike other types of posttranslational modifications occurred during stress responses, the role of p53 acetylation has been recently validated in vivo by using the knock-in mice with both acetylation-defective and acetylation-mimicking p53 mutants. Here, we review the r
