CC   -!- FUNCTION: Stimulates insulin release from beta cells at a concentration
CC       of 100 nM and release of glucagon-like peptide 1 (GLP-1) from
CC       enteroendocrine cells at a concentration of 1 uM in vitro. Reduces
CC       secretion of interferon gamma from peritoneal cells in a mouse model.
CC       Has no inhibitory activity against Gram-positive bacterium B.megaterium
CC       Bm11 or Gram-negative bacterium E.coli ATCC 25922 at concentrations of
CC       up to 100uM. Has no hemolytic activity against mouse erythrocytes.
CC       {ECO:0000269|PubMed:27560386}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:27560386}.
CC   -!- TISSUE SPECIFICITY: Expressed by the skin glands.
CC       {ECO:0000305|PubMed:27560386}.
