One letter sequence : AFTCHCRRSCYSTEYSYGTCTVMGINHRFCCL(Cys4 and Cys31/Cys6 and Cys20/Cys10 and Cys30 Bridge)
Molecular Formula : C156H228N46O46S7
Description : Cysteine-rich cationic peptide with antiviral activity against HSV infection and a role in N. gonorrhoeae-mediated HIV enhancement. In contrast to the other members of the ƒ-defensin family it shows very low antimicrobial activity against Gram-negative and Gram-positive bacteria. As a biomarker of colon adenocarcinoma it may have utility in colon cancer screening and diagnosis.
