p73γ is a member of the p53 family of transcription factors which are involved in cellular responses to stress and development. There are four isoforms of p73 (p73α, p73β, p73δ and p73γ) which differed in their abilities to form homodimeric and heterodimeric interactions with each other and with p53. The p73 isoforms also differed in their abilities to activate transcription of the p21(Waf1) promoter and to inhibit colony formation. The p73 protein is expressed at very low levels in normal tissues and is differentially expressed in a number of tumors. p73 is a stress-response gene that activates transcription of p53-responsive genes and inhibits cell growth in a p53-like manner by inducing apoptosis.
The protein p53 is the most frequently mutated tumour suppressor to be identified so far in human cancers. The ability of p53 to inhibit cell growth is due, at least in part, to its ability to bind to specific DNA

p73 has been recently identified as a new structural and functional homologue of the transcription factor p53. It is expressed in either a full-length form, alpha, or a shorter beta mRNA variant, with exon 13 spliced out. Here we report
