Peptide with both antimicrobial and neurotoxin activities. Cationic AMP with antibacterial activity against both Gram-positive bacteria (B.subtilis, MIC=11.49 ug/mL) and Gram-negative bacteria (E.coli (MIC=12.21 ug/mL) and S.enterica (MIC=11.95 ug/mL)) (PubMed:28796463). Shows no significant antimicrobial activity against bacteria S.aureus and P.aeruginosa, as well as the fungus C.albicans (PubMed:28796463). In vivo, induces reversible paralytic activity towards the shrimp P.paucidens (PubMed:28796463). May act by impairing sodium or potassium channels in the prey (Probable). Highly expressed by the mesenteries. Moderately expressed by the pharynx. Weakly expressed by the gonad and pedal disk. No expression in tentacle. Transcriptionally up-regulated by immune challenge. PD(50) is 0.84 +- 0.16 ug/g body weight when injected into the shrimp P.paucidens. The minimum paralytic dose is 2 ug/g body weight shrimp body weight. Belongs to the sea anemone type 3 (BDS) potassium channel toxin family.
