Broadly cross-reactive monoclonal antibodies define epitopes for vaccine development against HIV and other highly mutable viruses. Crystal structures are available for several such antibody-epitope complexes, but methods are needed to translate that structural information into immunogens that re-elicit similar antibodies. We describe a general computational method to design epitope-scaffolds in...
Calponin is an actin filament-associated protein found in smooth muscle and non-muscle cells. Calponin inhibits actin-myosin interaction in a manner that is prevented by protein kinase C (PKC)-catalysed phosphorylation of serine-175. To investigate the molecular basis of serine-175-mediated regulation, we examined the effect of phosphorylation on the conformation of calponin using monoclonal an...
Identifying localized changes in large systems: Change-point detection for biomolecular simulations.
Research on change-point detection, the classical problem of detecting abrupt changes in sequential data, has focused predominantly on datasets with a single observable. A growing number of time series datasets, however, involve many observables, often with the property that a given change typically affects only a few of the observables. We introduce a general statistical method that, given man...
Norovirus, which belongs to the family Caliciviridae, is one of the major causes of nonbacterial acute gastroenteritis in the world. The main human noroviruses are of genogroup I (GI) and genogroup II (GII), which were subdivided further into at least 15 and 18 genotypes (GI/1 to GI/15 and GII/1 to GII/18), respectively. The development of immunological diagnosis for norovirus had been hindered...
Immunogenic C. coli CjaA protein is a candidate for a chicken anti-Campylobacter subunit vaccine. In order to enhance its immunogenicity an antigenic determinant of the CjaA protein was identified. Thereafter, two copies of the antigenic epitope were cloned in tandem directly or with a flexible hinge between them. All experiments documented that the CjaA protein contained not only linear antige...
Mutations in the epitopes of antigenic proteins can confer viral resistance to antibody-mediated neutralization. However, the fundamental properties that characterize epitope residues and how mutations affect antibody binding to alter virus susceptibility to neutralization remain largely unknown. To address these questions, we used an ensemble-based algorithm to characterize the effects of muta...
When Glu-plasminogen binds to cells, its activation to plasmin is markedly enhanced compared with the reaction in solution, suggesting that Glu-plasminogen on cell surfaces adopts a conformation distinct from that in solution. However, direct evidence for such conformational changes has not been obtained. Therefore, we developed anti-plasminogen mAbs to test the hypothesis that Glu-plasminogen ...
