ASPP (ankyrin-repeat-, SH3-domain-proline-rich-region protein)proteins (ASPP1, ASPP2 and iASPP)represent a new family of p53 binding proteins.
ASPP1 and ASPP2 bind and enhance p53-mediated apoptosis.
In contrast, iASPP functionally inactivates p53.
ASPPs may also regulate p63- and p73-mediated apoptosis.
Both ASPP1 and 2 directly interact with p53 and specifically enhance the apoptotic function of p53 by stimulating its DNA binding and transactivation function on promoters of pro-apoptotic genes, such as Bax and PIG-3.
Not all cell cycle arrest genes are affected, such as p21.
Interestingly, expression of ASPP is frequently down-regulated in human breast carcinomas expressing wild-type p53 but not mutant p53.
Therefore, ASPP might regulate the tumor suppression function of p53 in vivo.
