CC   -!- FUNCTION: In muscle, parvalbumin is thought to be involved in
CC       relaxation after contraction. It binds two calcium ions.
CC   -!- MISCELLANEOUS: Three parvalbumin isotypes, in nearly equal proportion,
CC       are found in toadfish white trunk muscle whereas only one main
CC       component (IIIF) is present in the swimbladder muscle of adult
CC       specimens.
CC   -!- SIMILARITY: Belongs to the parvalbumin family. {ECO:0000305}.
