Sequence  LPLPAPSFHRTT

Sequence Length  12

UniProt ID  No entry found

Source  Synthetic construct(phage display)



Activity Information


Target Organism  HIV

Assay  Affinity binding assay

Activity 

  • [Ref.12480936]HIV-1:inhibition of Vif-Vif bingding(IC50=4.84 μM);
  • The peptide is able to effectively inhibit HIV-1 replication At the concentration of 50 μM.

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

Cytotoxicity 

  • [Ref.12480936]No significant cytotoxicity on H9 cells up to 50 μM.

Binding Target  Vif proteins

Mechanism  Vif proteins are essential for HIV-1 replication and able to form multimer, which is critical to the biological activity of many prokaryotic and eukaryotic proteins and is a common mechanism for the functional activation/inactivation of proteins.The peptide could bind with vif proteins and block the multimerization of them,which should inhibit HIV-1 replication.
