P53
Tumor protein p53, also known as p53, cellular tumor antigen p53 (UniProt name), phosphoprotein p53, tumor suppressor p53, antigen NY-CO-13, or transformation-related protein 53 (TRP53), is any isoform of a protein encoded by homologous genes in various organisms, such as TP53 (humans) and Trp53 (mice). This homolog (originally thought to be, and often spoken of as, a single protein) is crucial in multicellular organisms, where it prevents cancer formation, thus, functions as a tumor suppressor. As such, p53 has been described as ""the guardian of the genome"" because of its role in conserving stability by preventing genome mutation. Hence TP53 is classified as a tumor suppressor gene.The name p53 was given in 1979 describing the apparent molecular mass; SDS-PAGE analysis indicates that it is a 53-kilodalton (kDa) protein. In addition to the full length protein, the human TP53 gene encodes at least 15 protein isoforms, ranging in size from 3.5 to 53 kDa. All these p53 proteins are called the p53 isoforms.The International Cancer Genome Consortium has established that the TP53 gene is the most frequently mutated gene (>50%) in human cancer, indicating that the TP53 gene plays a crucial role in preventing cancer formation.TP53 gene encodes proteins that bind to DNA and regulate gene expression to prevent mutations of the genome.
