          Abstract

          Eggs are widely consumed all over the world. The eggshell is its protective barrier whose original function is to protect the embryo during development. Avian eggshells are made of calcium carbonate with a small amount of organic matrix (proteins and proteoglycans). During eggshell formation, the mineral precursors interact with matrix proteins to regulate the calcification of this highly resistant biomineral. In order to better characterize the functions of matrix proteins in eggshell biominerals, many proteomics studies have been performed during the last 15 years. The chicken eggshell is the main model studied in birds, but there is a need for comparative approaches in order to determine whether there is a general protein toolkits associated with calcitic biomineralization, and to determine its components. The study by Zhu et al., reported in article number 1900011, volume 19, issue 11, is a major step forward as it is the first shell proteomics survey performed on duck. Thus, it will contribute to improved knowledge of the eggshell mineralization process and will provide new insight for shell quality improvement and to guide biomimetic efforts in material sciences.
