Properties |  Tumor protein p53, also known as p53, cellular tumor antigen p53, 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 is crucial in multicellular organisms, where it prevents cancer formation. Thus, it functions as a tumor suppressor. TP53 is classified as a tumor suppressor gene. |
