RT   "Bradykinin-related peptides in skin secretion of Physalaemus signifer
RT   (Girard, 1853) (Anura, Leiuperidae).";
RL   Submitted (SEP-2010) to UniProtKB.
CC   -!- FUNCTION: Produces in vitro relaxation of rat arterial smooth muscle
CC       and constriction of intestinal smooth muscle (By similarity). May
CC       target bradykinin receptors (BDKRB). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000269|Ref.1}.
CC   -!- TISSUE SPECIFICITY: Expressed by the skin glands. {ECO:0000269|Ref.1}.
CC   -!- SIMILARITY: Belongs to the bradykinin-related peptide family.
CC       {ECO:0000305}.
