Anti-microbial-activity-associated peptides, including AKRHHGYKRKFH from anti-microbial histatin 5-derived P-113 (MAP-FP-1) [24], LKKLAKLALAF from anti-cancer peptide (MAP-FP-2) [25], THRPPMWSPVWP from transferrin receptor binding peptide (MAP-FP-3) [26,27], ILRWPWWPWRRK from anti-microbial omiganan (MAP-FP-4) [28,29], and KLAKLAKKLAKLAK from proapoptotic/anti-microbial KLAK peptide (MAP-FP-5) [30,31], were selected for MAP-fused functional peptides (MAP-FPs) (Table 1). This evidence concerns the gene HTN3 and cancer.
