    ..The previous findings that 53BP2 bound to p53 and Bcl-2 together with our present observations suggest that 53BP2 may play a central role in the regulation of apoptosis and cell growth. ..

    ..How p53 is able to discriminate between these different loci is the subject of intense research. Here, we describe key aspects of the fundamentals of p53-mediated transcriptional regulation and target gene promoter selectivity. ..

    ..Our study demonstrates a novel role for ASPP1 and ASPP2 in the death of RGCs and provides evidence that blockade of the ASPP-p53 pathway is beneficial for central neuron survival after axonal injury. ..

    ..The expression of ASPP is frequently downregulated in human breast carcinomas expressing wild-type p53 but not mutant p53. Therefore, ASPP regulate the tumor suppression function of p53 in vivo. ..

    ..In addition, ASPP2 is found in cytoplasm and nucleus at low Ddx42p level, and predominantly in cytoplasm at high concentration of Ddx42p, respectively. Our results show that Ddx42p is capable of modulating ASPP2 function. ..

    ..Because 53BP2 also interacts with p53 and Bcl2 and regulates p53 function, our results suggest that APCL might be involved in the p53/Bcl2-linked pathway of cell-cycle progression and cell death. ..

    ..These provide the first genetic evidence that ASPP2 is a haploinsufficient tumor suppressor that shares overlapping function(s) with p53 in mouse development and tumor suppression. ..

    ..Based on our results, we propose a model in which the interaction between the ASPP2 domains regulates the intermolecular interactions of ASPP2 with its partner proteins. ..
