P53 is a tumor suppressor protein encoded by the TP53 gene, often referred to as the “guardian of the genome” due to its critical role in maintaining genomic stability. It functions primarily as a transcription factor that responds to various cellular stresses—such as DNA damage, hypoxia, or oncogene activation—by regulating the expression of genes involved in cell cycle arrest, DNA repair, senescence, and apoptosis. By preventing the proliferation of damaged or abnormal cells, p53 plays a central role in suppressing tumor development.
Mutations in the TP53 gene are among the most common genetic alterations in human cancers, occurring in over 50% of malignancies across diverse tissue types. These mutations often lead to loss of p53 function or gain of oncogenic properties, contributing to uncontrolled cell growth and tumor progression. Due to its pivotal role in cancer biology, p53 is a major focus in cancer research, biomarker development, and therapeutic strategies, including efforts to restore its function or target p53-related pathways in oncology.
