CC -!- FUNCTION: [Bombinin-like peptide 7]: Antimicrobial peptide with
CC activity against Gram-positive and -negative bacteria and fungi
CC (PubMed:22439858, PubMed:32540219). Shows activity against P.acnes
CC (MIC=5 uM), E.coli (MIC=5-6.3 uM), S.aureus (MIC=5-6.3 uM), M.luteus,
CC S.cerevisiae and C.albicans (MIC=10-12.5 uM) (PubMed:22439858,
CC PubMed:28636781, PubMed:32540219). Also reduces the production of
CC interleukin (IL)-8 and granulocyte-macrophage colony stimulating factor
CC (CSF2) in normal human epidermal keratinocytes (NHEKs)
CC (PubMed:32540219). Shows anticancer activity against three human
CC hepatoma cell lines (PubMed:28636781). In vivo, using the rat ear edema
CC model, suppress P.acnes-induced skin inflammation, significantly
CC reducing the ear thickness (PubMed:32540219). Shows weak hemolytic
CC activity against human erythrocytes (PubMed:28636781).
CC {ECO:0000269|PubMed:22439858, ECO:0000269|PubMed:28636781,
CC ECO:0000269|PubMed:32540219}.
CC -!- FUNCTION: [Bombinin H-BO]: Shows weak antimicrobial activity (tested on
CC E.coli, S.aureus and C.albicans) (PubMed:28636781). Shows high
CC hemolytic activity against human erythrocytes (38% erythrocyte lysis at
CC 80.0 uM, and up to 85% at 159.7 uM) (PubMed:28636781).
CC {ECO:0000269|PubMed:28636781}.
CC -!- BIOPHYSICOCHEMICAL PROPERTIES: [Bombinin-like peptide 7]:
CC pH dependence:
CC Stable from pH 3.0 to 12.0. {ECO:0000269|PubMed:32540219};
CC Temperature dependence:
CC Highly thermostable, when continuously exposed at the temperatures
CC ranging from 20 to 100 degrees Celsius for 30 minutes.
CC {ECO:0000269|PubMed:32540219};
CC -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305|PubMed:32540219}.
CC -!- TISSUE SPECIFICITY: Expressed by the skin glands.
CC {ECO:0000305|PubMed:32540219}.
CC -!- MASS SPECTROMETRY: [Bombinin-like peptide 7]: Mass=2551.01;
CC Method=Electrospray; Evidence={ECO:0000269|PubMed:28636781};
CC -!- MASS SPECTROMETRY: [Bombinin H-BO]: Mass=1603.08; Method=Electrospray;
CC Evidence={ECO:0000269|PubMed:28636781};
CC -!- PHARMACEUTICAL: [Bombinin-like peptide 7]: Could be used as a potential
CC agent in the treatment against acne, since it shows antibacterial
CC activity against P.acnes and it both reduces the production of pro-
CC inflammatory cytokines and the skin inflammation induced by P.acnes in
CC rat ear edema model. {ECO:0000305|PubMed:32540219}.
CC -!- MISCELLANEOUS: BLP-7 is also encoded by another gene from the same
CC species (AC Q9DET7). {ECO:0000305}.
CC -!- SIMILARITY: Belongs to the bombinin family. {ECO:0000305}.
