Development
The Trp53- mice were developed by Beijing Biocytogen Co., Ltd. The targeted mouse Trp53 exons 2-7 were replaced with pGK-Neo cassette resulting in inactivation of Trp53 protein. The C57BL/6 ES cell line was used.

Description

The Trp53 gene encodes tumor protein p53, which involves in diverse cellular stresses to regulate target genes that induce cell cycle arrest, apoptosis, senescence, DNA repair, or changes in metabolism. P53 protein is expressed at low level in normal cells and at a high level in a variety of transformed cell lines. Mice with homozygous p53 inactivation are developmentally normal but are susceptible to spontaneous tumors.
