α-Aminoisobutyric acid incorporation induces cell permeability and antiviral activity of HIV-1 major homology region fragments

The design of a cell penetrating antiviral peptide, which is derived from the major homology region of HIV-1 capsid protein and includes the non-coded alpha-aminoisobutyric acid, provides functional evidence for the role of the conserved region in the HIV assembly process and demonstrates the correlation between conformational stability and cellular permeability.
