PVA is involved in calcium signaling. PVA contains 3 domains each containing 2 helices: AB, CD (N-terminal) and EF (C-terminal). α-parvalbumin differs from β-parvalbumin in 54 positions. α-parvalbumin is expressed in various tissues while β-parvalbumin is expressed only in preterm placenta. See also EF hand Parvalbumin carp. Relevance PVA is a major fish allergen. Structural highlights PVA contains a heptacoordinated Ca+2 ion binding to 7 oxygen atoms in a typical EF-hand coordination. Calcium ion is coordinated by seven oxygen atoms that form a pentagonal bipyramid . Ammonium ion coordination site. Water molecules shown as red spheres.
