NCIt synonyms : Tumor Protein p73 wt Allele; TRP73, Mouse, Homolog of Gene;
NCIt definition : Human TP73 wild-type allele is located in the vicinity of 1p36.33 and is approximately
1 kb in length. This allele, which encodes tumor protein p73, plays a role in the
cell cycle and is frequently deleted in neuroblastoma and other cancers.;
NCIt note : The tumor suppressor TP73 gene encodes a 73 kD protein with sequence similarity to
p53. p53 residues implicated in DNA binding are conserved in p73, which appears to
activate some p53-responsive genes and to induce apoptosis. p73 and c-ABL may participate
in a mismatch repair-dependent pro-apoptotic signaling pathway. T-cells undergoing
TCR-AICD, in a late G1 cell-cycle checkpoint, are dependent on E2F1 and TP73. Expression
of E2F1 causes accumulation of p73.;
