Assembly Models of P7 Protein From HCV

Docking assay of small molecule antivirals to p7 of HCV

Protein p7 of HCV is a 63 amino acid channel forming membrane protein essential for the progression of viral infection. With this momentousness, p7 emerges as an important target for antiviral therapy. A series of small molecule drugs, such as amantadine, rimantadine, amiloride, hexamethylene amiloride, NN-DNJ and BIT225 have been found to affect the channel activity. These compounds are docked...

Long alkylchain iminosugars block the HCV p7 ion channel.

Computational modeling of the p7 monomer from HCV and its interaction with small molecule drugs

Hepatitis C virus p7 protein is a 63 amino acid polytopic protein with two transmembrane domains (TMDs) and one of the prime targets for anti HCV drug development. A bio-inspired modeling pathway is used to generate plausible computational models of the two TMDs forming the monomeric protein model. A flexible region between Leu-13 and Gly-15 is identified for TMD11-32 and a region around Gly-46...

Hepatitis C Virus p7 Protein Is Crucial for Assembly and Release of Infectious Virions

Hepatitis C virus (HCV) infection is associated with chronic liver disease and currently affects about 3% of the world population. Although much has been learned about the function of individual viral proteins, the role of the HCV p7 protein in virus replication is not known. Recent data, however, suggest that it forms ion channels that may be targeted by antiviral compounds. Moreover, this pro...

Mechanisms of protein assembly: lessons from minimalist models.

Many cellular functions rely on interactions among proteins and between proteins and nucleic acids. The limited success of binding predictions may suggest that the physical and chemical principles of protein binding have to be revisited to correctly capture the essence of protein recognition. In this Account, we discuss the power of reduced models to study the physics of protein assembly. Since...
