Asprich: A Novel Aspartic Acid‐Rich Protein Family from the Prismatic Shell Matrix of the Bivalve Atrina rigida

Almost all mineralized tissues contain proteins that are unusually acidic. As they are also often intimately associated with the mineral phase, they are thought to fulfill important functions in controlling mineral formation. Relatively little is known about these important proteins, because their acidic nature causes technical difficulties during purification and characterization procedures. Much effort has been made to overcome these problems,...
