PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • a 22 aa signal peptide
    • isoforms Precursor potential mature peptide of 55 aa
    HOMOLOGY
    interspecies homolog to murine leap2 (85.5 pc)
    Homologene
    FAMILY
  • LEAP2 family
    • CATEGORY immunity/defense
    SUBCELLULAR LOCALIZATION extracellular
    basic FUNCTION
  • having an antimicrobial activity
  • involved in defense response to bacterium
  • plasma LEAP2/acyl-ghrelin molar ratio may likely be a key determinant modulating acyl-ghrelin activity in response to body mass, feeding status, and blood glucose
    • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS immunity/defense
    PATHWAY
    metabolism
    signaling
    a component
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • LEAP2 fully inhibits GHSR activation by ghrelin and blocks the major effects of ghrelin, including food intake, GH release, and maintenance of viable glucose levels during chronic caloric restriction

    Candidate gene
    Marker
  • LEAP2 may have potential as a biomarker for bacterial meningitis
    • Therapy target
    ANIMAL & CELL MODELS
  • in female mice, LEAP2 deletion increases body length and exaggerates the hepatic fat accumulation normally associated with chronic high-fat diet feeding
