RT   skin confirms a non-consensus tyrosine 0-sulfation motif.";
RL   Peptides 24:1123-1130(2003).
CC   -!- FUNCTION: May produce in vitro relaxation of rat arterial smooth muscle
CC       and constriction of intestinal smooth muscle. May target bradykinin
CC       receptors (BDKRB).
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000305}.
CC   -!- TISSUE SPECIFICITY: Expressed by the skin glands. {ECO:0000305}.
CC   -!- MASS SPECTROMETRY: Mass=1059.45; Method=MALDI;
CC       Evidence={ECO:0000269|PubMed:14612182};
CC   -!- SIMILARITY: Belongs to the bradykinin-related peptide family.
CC       {ECO:0000305}.
