CC   -!- FUNCTION: Tachykinins are active peptides which excite neurons, evoke
CC       behavioral responses, are potent vasodilators and secretagogues, and
CC       contract (directly or indirectly) many smooth muscles.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- SIMILARITY: Belongs to the tachykinin family. {ECO:0000305}.
