<P> 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 . ( Italics are used to denote the TP53 gene name and distinguish it from the protein it encodes . ) </P>
