Activity

Neurotoxin
FUNCTION: Cationic peptide that possesses multiple functions. It acts as a cell-penetrating peptide (CPP), and as a potent voltage-gated potassium channel (Kv) inhibitor. It exhibits antimicrobial activities, hind limb paralysis, and severe muscle necrosis by a non-enzymatic mechanism. {ECO:0000250|UniProtKB:Q9PWF3}.

Target

voltage-gated potassium channel (Kv)
