Figure 4. Effect of mutation of surface-exposed cationic residues.
A: The comparison of surface-exposed cationic residues of SDF-1 (left) and hBD-3 (right). Panels B through F show the inhibition of SDF-1α-triggered Ca2+ mobilization by hBD-3 mutants. B: mutant K8A; C: mutant K32S; D: mutant R36I; E: mutant 8–32 (K8A/K32S); F: mutant 8-32-36 (K8A/K32S/R36I); G: inhibition of high-affinity SDF-1α binding by 8-32-36.
