CC   -!- FUNCTION: Causes a rapid but short-lived drop in the level of calcium
CC       and phosphate in blood by promoting the incorporation of those ions in
CC       the bones.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- MISCELLANEOUS: Calcitonin 1 is less active than calcitonins 1 or 2.
CC       Only this species of salmon possesses calcitonin 3.
CC   -!- SIMILARITY: Belongs to the calcitonin family. {ECO:0000305}.
