UniProt ID  No entry found

Source  Synthetic construct(derived from HIV-1 gene products(Vpr))

Target Organism  HIV

Assay  Luciferase assay

Activity 

• [Ref.20586421]HIV-1:Inhibition of 3′-end processing catalyzed by integrase(IC50=0.70±0.06 µM);inhibition of strand transfer catalyzed by integrase(IC50=0.83±0.07 µM).

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

Cytotoxicity 

• No cytotoxicity information or data found in the reference(s) presented in this entry

Binding Target  Integrase

Mechanism  IN is an essential enzyme for the stable infection of host cells because it catalyzes the insertion of viral DNA inside the pre-integration complex (PIC) into the genome of host cells in two successive reactions, designated as strand transfer and 3′-end-processing. The peptide could inhibit the activity of integrase and thus inhibit virus replication.
