Protein-Protein Interactions Inferred from Domain-Domain Interactions in Genogroup II Genotype 4 Norovirus Sequences

Abstract EN

Severe gastroenteritis and foodborne illness caused by Noroviruses (NoVs) during the winter are a worldwide phenomenon.

Vulnerable populations including young children and elderly and immunocompromised people often require hospitalization and may die.

However, no efficient vaccine for NoVs exists because of their variable genome sequences.

This study investigates the infection processes in protein-protein interactions between hosts and NoVs.

Protein-protein interactions were collected from related Pfam NoV domains.

The related Pfam domains were accumulated incrementally from the protein domain interaction database.

To examine the influence of domain intimacy, the 7 NoV domains were grouped by depth.

The number of domain-domain interactions increased exponentially as the depth increased.

Many protein-protein interactions were relevant; therefore, cloud techniques were used to analyze data because of their computational capacity.

The infection relationship between hosts and NoVs should be used in clinical applications and drug design.
