From Wikipedia, the free encyclopedia

The p53 p63 p73 family is a family of tumor suppressor genes. [1] [2]

This gene family codes the proteins:

They are sometimes considered part of a "p53 family." When overexpressed, these proteins are known to be involved in tumor pathogenesis. [3]

Evolution

P53, p63, and p73 have similar features in their gene structures and functions but have also diverged evolutionarily. The p53 family evolved from an ancestor gene in unicellular life. [4] The ancestor gene functioned in germ line DNA protection early invertebrates. [5] In invertebrates, the ancestor gene resembled p63/p73 as it contained the sterile alpha motif (SAM) domain. [6] P53 diverged from p63/p73 with a gene duplication in the cartilaginous fish. [7] P63 and p73 differentiated from each other in bony fish. [7] In vertebrates, p53 began the role of protecting the somatic cells and acting as a tumor suppressor. [8] [7]
