摘要 p53凋亡刺激蛋白(apoptosis sti mulating protein of p53,ASPP)家族是近年来发现的一个新蛋白家族,它包括3个成员:ASPP1、ASPP2和i ASPP。其中ASPP1和ASPP2能够与p53蛋白结合增强该蛋白的促进细胞凋亡的功能,发挥抑制肿瘤的作用;而i ASPP与ASPP1和ASPP2的功能截然相反,它能够和ASPP1或ASPP2竞争性地与p53结合,抑制ASPP1或ASPP2的促进凋亡作用,具有癌基因的功能。三者的结构相似,但功能却完全不同,通过研究三者的关系、促进肿瘤细胞内ASPP1或ASPP2的高表达以及抑制i ASPP的表达有可能促进肿瘤细胞的凋亡,成为肿瘤治疗的新靶点。
