Protein flexibility directs DNA recognition by the papillomavirus E2 proteins (2010)
Journal Article
Brown, C. A., Campos-León, K., Strickland, M., Williams, C., Fairweather, V., Brady, R. L., …Gaston, K. (2011). Protein flexibility directs DNA recognition by the papillomavirus E2 proteins. Nucleic Acids Research, 39(7), 2969--2980. https://doi.org/10.1093/nar/gkq1217

Although DNA flexibility is known to play an important role in DNA–protein interactions, the importance of protein flexibility is less well understood. Here, we show that protein dynamics are important in DNA recognition using the well-characterized... Read More about Protein flexibility directs DNA recognition by the papillomavirus E2 proteins.

Protein self-organization is essential for the establishment and maintenance of nuclear architecture and for the regulation of gene expression. We have shown previously that the Proline-Rich Homeodomain protein (PRH/Hex) self-assembles to form oligom...

Protein function is intimately coupled to protein localization. Although some proteins are restricted to a specific location or subcellular compartment, many proteins are present as a freely diffusing population in free exchange with a sub-population...

The proline-rich homeodomain protein (PRH) plays multiple roles in the control of gene expression during embryonic development and in the adult. Vascular endothelial growth factor (VEGF) is a mitogen that stimulates cell proliferation and survival vi...

The human papillomavirus E7-E2 interaction mechanism in vitro reveals a finely turned system for modulating available E7 and E2 proteins (2009)
Journal Article
Smal, C., Wetzler, D. E., Dantur, K. I., Chemes, L. B., Garcia-Alai, M. M., Dellarole, M., …de Prat Gay, G. (2009). The human papillomavirus E7-E2 interaction mechanism in vitro reveals a finely turned system for modulating available E7 and E2 proteins. Biochemistry, 48(50), 11939-11949. https://doi.org/10.1021/bi901415k

Transcription of the human papillomavirus E7 oncoprotein is negatively controlled by the viral E2 protein, and loss of this repression leads to irreversible transformation and carcinogenesis. Here we show that interaction of the HPV16 E7 protein with...

The proline-rich homeodomain protein (PRH/Hex) regulates transcription by binding to specific DNA sequences and regulates mRNA transport by binding to translation initiation factor eIF4E. Protein kinase CK2 plays multiple roles in the regulation of g... Read More about CK2 phosphorylation of the PRH/Hex homeodomain functions as a reversible switch for DNA binding.

The regulation of cell proliferation by the papillomavirus early proteins (2009)
Journal Article

The human papillomavirus (HPV) E6 and E7 oncogenes have direct effects on host cell proliferation. The viral E2 protein regulates transcription of E6 and E7 and thereby has an indirect effect on cell proliferation. In HPV-induced tumours, misappropri...
