A novel antimicrobial peptide, hdMolluscidin, was isolated and cloned from the gill of the abalone, Haliotis discus.
hdMolluscidin consists of 46 amino acids with 4767.2 Da molecular mass as a linear form.
hdMolluscidin was constitutively expressed as a mature form in the gill tissue.
hdMolluscidin showed broad and potent antimicrobial spectrum without hemolysis and may target intracellular components.
hdMolluscidin play an important role in the innate defenses of the abalone.
