Biominéralisation chez les Céphalopodes (Mollusca) : processus moléculaires et évolution
2021
Molluscs constitute one of the most diversified phyla within metazoans, known for their ability to mineralize a shell. The shell biomineralization is a genetically controlled process that is performed extracellularly via a calcifying organic matrix. This latter, which remains finally occluded (at least, partially) into the shell, is a mixture of proteins, glycoproteins, lipids and polysaccharides, that are collectively secreted by the external calcifying epithelium of the mantle. Today, the shell matrix is usually considered as the ‘molecular toolbox’ for constructing the shell. Since its discovery, it has been the focus of numerous studies, but mainly on bivalves and gastropods leaving cep…
