CC   -!- FUNCTION: In muscle, parvalbumin is thought to be involved in
CC       relaxation after contraction. It binds two calcium ions (By
CC       similarity). {ECO:0000250|UniProtKB:P02622,
CC       ECO:0000250|UniProtKB:P02624}.
CC   -!- MISCELLANEOUS: Is regarded as an important allergen.
CC       {ECO:0000250|UniProtKB:P02622, ECO:0000269|PubMed:20586483}.
CC   -!- MISCELLANEOUS: On the 2D-gel the determined pI of this protein is:
CC       3.92, its MW is: 11.37 kDa. {ECO:0000269|PubMed:20586483}.
CC   -!- SIMILARITY: Belongs to the parvalbumin family. {ECO:0000255}.
