p73 delta N antibody [38C674.2],Genetex,GTX11997

Even though the tumor suppressor gene p53 is highly important in human cancer, as indicated by the fact that it is mutated in about 50% of cases, up to a few years ago no similar proteins had been identified. Two p53 homologues are now identified, p73 and p63, with high amino acid identity suggesting similar functions. Both p63 and p73 have two significant structural peculiarities compared with p53; the presence of an extended non-conserved C-terminus containing a sterile alpha motive (SAM), (typical of developmental proteins), and the presence of number of different splicing isoforms differing in the N-terminus or in the absence of the transactivation domain (delta N forms).
