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 -!- MASS SPECTROMETRY: Mass=11302.715; Mass_error=0.0144;
CC Method=Electrospray; Evidence={ECO:0000269|PubMed:20586483};
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 4.30, its MW is: 11.30 kDa. {ECO:0000269|PubMed:20586483}.
CC -!- SIMILARITY: Belongs to the parvalbumin family. {ECO:0000255}.
