Aspein is an unusually acidic bivalve shell matrix protein, which may have important roles in calcium carbonate biomineralization. The Aspein gene (aspein, Uniprot: Q76K52) encodes a sequence of 413 amino acids, including a high proportion of Asp (60.4%), Gly (16.0%), and Ser (13.2%), and the predicted isoelectric point is 1.78.
