Molluscan shell proteins

Open access
Marin, Frédéric, Luquet, Gilles·2004·Comptes Rendus Palevol

Abstract

The shell secreted by molluscs is one of the most remarkable examples of a matrix-mediated mineralisation performed outside living tissues. The calcifying matrix is a mixture of proteins, glycoproteins, and polysaccharides that precisely self-assemble and control the CaCO3 polymorph (calcite, aragonite), the size, the shapes of the crystallites, and finally, the texture of the shell. In spite of several biochemical studies, the molecular aspects of the shell building are far from being understood. The present article makes an overview of the most recent molecular data on the proteinaceous components of the shell matrix. These data put into question the classical models of molluscan mineralisation. Furthermore, they show that shell proteins are diverse and multifunctional and that they may have different origins.

La calcification de la coquille chez les mollusques est l’un des plus remarquables exemples d’une minéralisation régulée par une trame organique extracellulaire. Cette trame est un mélange de protéines, glycoprotéines et polysaccharides, qui s’auto-assemblent et contrôlent le polymorphe du CaCO3 (calcite ou aragonite), la taille, la forme des cristaux produits, mais aussi la texture de la coquille. Malgré de nombreuses caractérisations biochimiques, les aspects moléculaires de la fabrication de la coquille sont loin d’être compris. Le présent article fait le point sur les protéines coquillières connues chez les mollusques. Les données moléculaires remettent en question les modèles de biominéralisation de la coquille proposés jusqu’à présent et montrent que les protéines de coquille sont diversifiées et multifonctionnelles. Elles ont en outre plusieurs origines possibles. Pour citer cet article : F. Marin, G. Luquet, C. R. Palevol 3 (2004).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
