This family consists of several mammalian liver-expressed antimicrobial peptide 2 (LEAP-2) sequences. LEAP-2 is a cationic cysteine-rich protein. LEAP-2 contains a core structure with two disulfide bonds formed by cysteine residues in relative 1-3 and 2-4 positions. LEAP-2 is synthesised as a 77-residue precursor, which is predominantly expressed in the liver and highly conserved among mammals. The largest native LEAP-2 form of 40 amino acid residues is generated from the precursor at a putative cleavage site for a furin-like endoprotease. In contrast to smaller LEAP-2 variants, this peptide exhibits dose-dependent antimicrobial activity against selected microbial model organisms [PMID: 12493837].

The format for Signature ID is the family name, followed by H or P for HMM or Pattern respectively. The integer suffixed to H or P denotes the length of the sequences used to create the family signature. If no integer is suffixed, it indicates that the signature was created using all the sequences of the family. The integer following the underscore denotes the number of sequences used for the creation of signatures.

For example:
AureinH_21 is a HMM for Aurein family created using 21 sequences.
AureinP16_9 is a pattern for Aurein family derived using 9 input sequences that are 16 residues long.
