Aurein antibiotic peptide family (IPR013157)

Short name: Aurein_antimicrobial_peptide

Overlapping homologous superfamilies


Family relationships



This family of antibacterial peptides are secreted from the granular dorsal glands of Litoria aurea (Green and golden bell frog), Litoria raniformis (Southern bell frog), Litoria citropa (Australian blue mountains tree frog) and frogs from genus Uperoleia. They are a part of the FSAP peptide family. Amongst the more active of these are aurein 1.2, aurein 2.2 and aurein 3.1; caerin 1.1, maculatin 1.1, uperin 3.6 [PMID: 10951191]; citropin 1.1, citropin 1.2, citropin 1.3 and a minor peptide are wide-spectrum antibacterial peptides [PMID: 10504394].
