detection and display of p53 putative response elements (REs) on DNA sequences

Download this project as a .zip file Download this project as a tar.gz file


p53retriever is an R package implementing a pattern search algorithm that maps p53 response elements (REs) and ranks them according to predicted transactivation potentials in five classes. Besides canonical, full site REs, p53retriever contains specific pattern searches for non-canonical half sites and 3/4 sites. REs can be displayed along the input sequence in a graphical layout.

The rules formalized in the model are based on observations obtained during several years of experiments using the yeast-based assays, including the results presented in (Inga et al MCB2002; Tomso et al, PNAS 2005; Jegga et al PNAS 2008; Jordan et al PloS Genetics 2008; Menendez et PNAS 2010).
