Biology:P53 p63 p73 family

From HandWiki
Short description: Family of tumor suppressor genes

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

This gene family codes the proteins:

  • p53
  • TP73L (also known as "p63")
  • p73

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]
