Family

Liver-expressed antimicrobial peptide 2 (IPR009955)

Short name: LEAP-2

Family relationships

None.

Description

This family consists of several mammalian liver-expressed antimicrobial peptide 2 (LEAP-2) sequences. LEAP-2 is a cysteine-rich, and cationic protein. LEAP-2 contains a core structure with two disulphide 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 exact function of this family is unclear.
