Antimicrobial peptides from hylid and ranin frogs originated from a 150‐million‐year‐old ancestral precursor with a conserved signal peptide but a hypermutable antimicrobial domain

Abstract
The dermal glands of frogs produce antimicrobial peptides that protect the skin against noxious microorganisms and assist in wound repair. The sequences of these peptides are very dissimilar, both wi...
