The significance of appropriate p53 function is emphasized by its higher mutation frequency amongst human cancers (Hollstein et al., 1991; Levine et al., 1991; Petitjean et al., 2007) and the overexpression of `mutant’ p53 in certain tumors suggests that some mutations could have a dominant-negative effect on wildtype p53 (Goldstein et al., 2011; Oren and Rotter, 2010). Specific cancers which include melanomas harbor wildtype TP53, however, these tumors bypass the regulatory functions of p53 and continue to proliferate and metastasize (Albino et al., 1994; Gwosdz et al., 2006; Li et al., 2006; Montano et al., 1994; Soto et al., 2005; Weiss et al., 1995; Zerp et al., 1999). This poses the query of how melanoma cells continue to proliferate inside the presence of wildtype TP53. The TP53 gene encodes 12 protein isoforms that happen to be missing particular regions of full-length p53 (Marcel et al., 2011) and are capable of altering p53 function (Courtois et al., 2002; Ghosh et al., 2004; Khoury and Bourdon, 2010). Particular p53 isoforms happen to be identified in both cancer (Anensen et al., 2006; Avery-Kiejda et al., 2008; Boldrup et al., 2007; Bourdon et al., 2005b; Marcel et al., 2010; Takahashi et al., 2012) and non-cancerous tissues (Ungewitter and Scrable, 2010b). Among these isoforms, 40p53, is missing the initial 40 amino acids encoding the initial transactivation domain and may be sy.
