p53 is a well known tumor suppressor protein that plays a critical role in cell cycle arrest and apoptosis. It has several isoforms which are produced by transcriptional and posttranscriptional regulatory mechanisms. p53 mRNA has been demonstrated to be translated into two isoforms, full-length p53 (FL-p53) and a truncated isoform N-p53 by the use of alternative translation initiation sites. The mechanism of translation regulation of these two isoforms was further elucidated by the discovery of IRES elements in the p53 mRNA. These two IRESs were shown to regulate the translation of p53 and N-p53 in a distinct cell-cycle phase-dependent manner. This review focuses on the current understanding of the regulation of p53 IRES mediated translation and the role of cis and trans acting factors that influence expression of p53 isoforms.
