TP53, TP63, and TP73 genes comprise the p53 family. Each gene produces protein isoforms through multiple mechanisms including extensive alternative mRNA splicing. Accumulating evidence shows that these isoforms play a critical role in the regulation of many biological processes in normal cells. Their abnormal expression contributes to tumorigenesis and has a profound effect on tumor response to curative therapy. This paper is an overview of isoform diversity in the p53 family and its role in cancer.
TP53、TP63和TP73基因组成了p53家族。每个基因通过多种机制产生蛋白质异构体,包括广泛的可变mRNA剪接。越来越多的证据表明,这些异构体在正常细胞中许多生物学过程的调节中起着关键作用。它们的异常表达促进肿瘤发生,并对肿瘤对根治性治疗的反应产生深远影响。本文概述了p53家族中的异构体多样性及其在癌症中的作用。
