DRAVP ID DRAVPe01302
Peptide Name mHR2(derived from SARS-CoV spike protein heptad repeat)
Sequence DLSLDFEKLNVTLLDLTYEMNRIQDAIKKLNESYINLKE
Sequence Length 39
UniProt ID P11224
Source Synthetic construct(derived from SARS-CoV spike protein heptad repeat)
Activity Information
Target Organism SARS-CoV
Assay Indirect immunofluorescence assay
Activity
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 membrane
Mechanism The peptide exhibits antiviral activity by competitive binding to the HR11 region of the SARS-CoV spike protein, thus blocking the formation of the six-helix bundle and consequently membrane fusion.
