The native peptide is a cationic amphipathic alpha-helical antimicrobial peptide with potent activity against both Gram-positive and Gram-negative bacteria (By similarity). It has weak activity against fungi and shows low hemolytic activity (By similarity). Expressed by the skin glands. Plasticins have huge conformational plasticity. They can display random coil, alpha-helical, beta-sheet or beta-harpin structures. Belongs to the frog skin active peptide (FSAP) family. Plasticin subfamily.
