CC   -!- FUNCTION: Induces relaxation of mouse trachea that has been
CC       precontracted with methacholine. May induce relaxation of arterial
CC       smooth muscle. May target bradykinin receptors (BDKRB).
CC       {ECO:0000269|PubMed:15922344}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|PubMed:15922344}.
CC   -!- TISSUE SPECIFICITY: Expressed by the skin glands.
CC       {ECO:0000269|PubMed:15922344}.
CC   -!- MASS SPECTROMETRY: Mass=1273.7; Method=MALDI;
CC       Evidence={ECO:0000269|PubMed:15922344};
CC   -!- SIMILARITY: Belongs to the bradykinin-related peptide family.
