Sequence  TEPSTRGSWKFW

Sequence Length  12

UniProt ID  No entry found

Source  Synthetic construct(phage display)



Activity Information


Target Organism  JEV

Assay 

Activity 

  • [Ref.24468276]Japanese encephalitis virus (JEV): inhibition of JEV infection in BHK-21 cells(IC50~100 μM).

Hemolytic Activity  No hemolysis information or data found in the reference(s) presented in this entry

Cytotoxicity  No cytotoxicity information found in the reference(s) presented

Binding Target  envelope protein

Mechanism  E glycoprotein has been identified as the major antigenic determinant on flavivirus particles and mediates binding and fusion during viral entry,DIII has been proposed to act as the binding region for the cellular receptor. And the peptide could bingding with DIII domain and inhibit the initial step of JEV infection.
