NCIt definition : Human TP53 wild-type allele is located in the vicinity of 17p13.1 and is approximately
19 kb in length. This allele, which encodes cellular tumor antigen p53 protein, plays
a role in cell cycle regulation during the G0/G1transition. Alterations of the TP53
gene occur as both somatic and germline mutations in human malignancies in select
cancer-prone families with Li-Fraumeni syndrome.;
Alternative definition : NCI-GLOSS: A tumor suppressor gene that normally inhibits the growth of tumors. This
gene is altered in many types of cancer.;
