Human immunodeficiency virus type 1 (HIV-1) Tat repressed the p53-dependent gene expression through its C-terminal domain of Tat (amino acid residues 73-86) independent of the involvement of NF-kappaB and coactivator CBP/p300. Although Tat did not directly bind to p53, this repression required the N-terminal domain of p53. In contrast, Tat and p53 cooperated in the activation of HIV-1 gene expression. Thus, the cross-talk between Tat and p53 may be linked with cellular transformation by HIV-1 infection or activation of HIV-1 replication. 相似文献
