CC   -!- FUNCTION: In muscle, parvalbumin is thought to be involved in
CC       relaxation after contraction. It binds two calcium ions.
CC   -!- MASS SPECTROMETRY: Mass=11329.746; Mass_error=0.0013;
CC       Method=Electrospray; Evidence={ECO:0000269|PubMed:20586483};
CC   -!- MISCELLANEOUS: This is the major hake parvalbumin.
CC   -!- MISCELLANEOUS: This parvalbumin has an isoelectric point of 4.36.
CC   -!- MISCELLANEOUS: Is regarded as an important allergen.
CC   -!- SIMILARITY: Belongs to the parvalbumin family. {ECO:0000305}.
