NCIt definition : A synthetic agent derived from human papillomavirus (HPV) E7 nuclear protein which
is used to produce vaccines against HPV infection and HPV-related neoplasms. HPV E7
oncogenic protein binds the retinoblastoma tumor suppressor protein, pRB, as well
as a number of other cellular proteins, and serves as a transcriptional activator.
This protein is important in the induction and maintenance of cellular transformation
and is co-expressed in the majority of HPV-containing carcinomas. PADRE(R) is a proprietary
family of molecules that enhances the immune systems response against an administered
immunogen such as the HPV E7 nuclear protein. (NCI04);
