A Functional Epitope Determinant on Domain III of the Japanese Encephalitis Virus Envelope Protein Interacted with Neutralizing-Antibody Combining Sites
The envelope (E) protein of Japanese encephalitis virus (JEV) is associated with viral binding to cellular receptors, membrane fusion, and the induction of protective neutralizing-antibody responses in hosts. Most previous studies have not provided detailed molecular information about the spatial configuration of the functional epitopes on domain III of the E protein. Here site-directed mutagenesis was performed to demonstrate that the functional epitope determinants at Ser331 and Asp332 on domain III of the JEV E protein interacted with neutralizing monoclonal antibody (MAb) E3.3. Bacterial expression of the recombinant Fab E3.3 confirmed the molecular interactions of Arg94 in complementary determining region H3 with Ser331 and Asp332 on domain III. This study elucidates the detailed molecular structures of the neutralizing epitope determinants on JEV domain III, which can provide useful information for designing new vaccines.
This research output has an Altmetric Attention Score of 9. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 20 January 2026.
All research outputs
#5,046,170
of 34,054,827 outputs
Outputs from Journal of Virology
#5,530
of 30,171 outputs
Outputs of similar age
#17,899
of 212,448 outputs
Outputs of similar age from Journal of Virology
#61
of 295 outputs
Altmetric has tracked 34,054,827 research outputs across all sources so far. Compared to these this one has done well and is in the 83rd percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 30,171 research outputs from this source. They typically receive more attention than average, with a mean Attention Score of 8.7. This one has gotten more attention than average, scoring higher than 73% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 212,448 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 87% of its contemporaries.
We're also able to compare this research output to 295 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 68% of its contemporaries.
