Reаd this pаssаge frоm a research repоrt tо answer the question that follows:“Tumor protein p53, also known as p53, is crucial in multicellular organisms, where it prevents cancer formation, thus, functions as a tumor suppressor. The 3′ untranslated region of p53 mRNA represses translation. Here, we identify a cis-acting sequence in the human p53 mRNA 3′ untranslated region that mediates translational repression.” What type of regulatory molecule might be regulating the translation of p53?
