RL   Peptides 26:1120-1126(2005).
CC   -!- FUNCTION: Has antifungal activity against F.oxysporum, B.cinera and
CC       M.arachidicola with IC(50) values of 1.4 uM, 2.5 uM and 0.15 uM,
CC       respectively. Has antibacterial activity against the Gram-positive
CC       bacteria B.megaterium, B.subtilis and M.phlei, and the Gram-negative
CC       bacterium P.vulgaris. No antibacterial activity against the Gram-
CC       positive bacteria B.cereus and S.aureus, or the Gram-negative bacteria
CC       E.coli, E.aerogenes, P.aeruginosa and P.fluorescens. Has mitogenic
CC       activity towards murine splenocytes. Inhibits the proliferation of M1
CC       leukemia and MCF-7 breast cancer cells in vitro. Inhibits human
CC       immunodeficiency virus-1 (HIV-1) reverse transcriptase.
CC       {ECO:0000269|PubMed:15949629}.
CC   -!- SIMILARITY: Belongs to the DEFL family. {ECO:0000305}.
