Target Data

Function Participates in the apoptotic response to DNA damage. Isoforms containing the transactivation domain are pro-apoptotic, isoforms lacking the domain are anti-apoptotic and block the function of p53 and transactivating p73 isoforms. May be a tumor suppressor protein.
Gene References into Functions
  1. Data show that codon usage bias (CUB) was moderate in P73 gene and the percentage of mean C was the highest followed by G. The gene variants were GC rich. The GC-ending codons showed increasing usage with increasing GC3 while AT-ending codons showed the opposite with increasing GC3 bias. ATA and AGA were absent among the synonymous codons in P73 gene. Both mutation pressure and natural selection might influence the CUB. PMID: 30316927

NQO1 is a FAD-dependent, two-domain multifunctional stress protein acting as a Phase II enzyme, activating cancer pro-drugs and stabilizing p53 and p73a oncosuppressors.tructural protein:protein interaction studies reveal that the cancer-associated polymorphism does not abolish the interaction with p73alpha, indicating that oncosuppressor destabilization largely mirrors the low intracellular stability of p.P187S.

  19. p73 is epigenetically silenced in chondrosarcoma due to promoter methylation, which suggests the utility of p73 methylation as a biomarker. PMID: 28551631
  20. A considerable number of lymphoma patients lacked the expression of either or both isoforms, while all lymphoid leukemia patients expressed both isoforms. The expression pattern differences of p73 isoforms may reflect differences in the biology of these malignancies. PMID: 27103208
