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.
