title: Posttranscriptional regulation of p53 and its targets by RNA-binding proteins.
abstract: p53 tumor suppressor plays a pivotal role in maintaining genomic integrity and preventing cancer development. The importance of p53 in tumor suppression is illustrated by the observation that about 50% human tumor cells have a dysfunctional p53 pathway. Although it has been well accepted that the activity of p53 is mainly controlled through post-translational modifications, recent studies have revealed that posttranscriptional regulations of p53 by various RNA-binding proteins also play a crucial role in modulating p53 activity and its downstream targets.
