Bombinin-like peptide 7
Antimicrobial peptide with activity against Gram-positive and -negative bacteria and fungi (PubMed:22439858, PubMed:32540219).
Shows activity against P.acnes (MIC=5 uM), E.coli (MIC=5-6.3 uM), S.aureus (MIC=5-6.3 uM), M.luteus, S.cerevisiae and C.albicans (MIC=10-12.5 uM) (PubMed:22439858, PubMed:28636781, PubMed:32540219).
Also reduces the production of interleukin (IL)-8 and granulocyte-macrophage colony stimulating factor (CSF2) in normal human epidermal keratinocytes (NHEKs) (PubMed:32540219).
Shows anticancer activity against three human hepatoma cell lines (PubMed:28636781).
In vivo, using the rat ear edema model, suppress P.acnes-induced skin inflammation, significantly reducing the ear thickness (PubMed:32540219).
Shows weak hemolytic activity against human erythrocytes (PubMed:28636781).

Bombinin GH-2
Shows weak antimicrobial activity but high hemolytic activity.
Miscellaneous
BLP-7 is also encoded by another gene from the same species (AC A0A219CM62).
pH Dependence
Stable from pH 3.0 to 12.0.
Temperature Dependence
Highly thermostable, when continuously exposed at the temperatures ranging from 20 to 100 degrees Celsius for 30 minutes.

Phenotypes & Variants
Pharmaceutical
Bombinin-like peptide 7
Could be used as a potential agent in the treatment against acne, since it shows antibacterial activity against P.acnes and it both reduces the production of pro-inflammatory cytokines and the skin inflammation induced by P.acnes in rat ear edema model.
