DRAMP01556

DRAMP01556 chydropathy plot
    • Function

    • Antibacterial peptide, that adopts an alpha helical conformation which can disrupt bacterial membranes. Each caerin displays a different antimicrobial specificity.
    • Tissue specificity

    • Expressed by the skin dorsal glands.
    • Domain

    • Contains two amphipathic alpha helix regions separated by a region of less-defined helicity and greater flexibility By similarity.
    • PTM

    • C-terminal amidation.
