The text discusses the TP53 gene, which codes for the protein p53 - a tumor suppressor protein involved in regulating cell growth and preventing cancer development. The gene is located on chromosome 17 and its nucleotide sequence can be found in databases. The p53 protein has different domains that are involved in transcriptional activation, DNA binding, and oligomerization. It forms complexes with other proteins, such as AXIN1 and HIPK2. Mutations in the gene, particularly in the core domain, can lead to malfunctioning of the p53 protein and increase the risk of cancer.
