Mollusc shells consist of the nacreous mother-of-pearl layer and the prismatic layer. Both layers are microlaminate composites of CaCO3 crystals (aragonite in the nacre and calcite in the prismatic layer) and biopolymers. The main biopolymers are structural proteins, insoluble in water and methanoic acid, which determine the framework of each shell layer and bind soluble polyanionic proteins which determine the type of CaCO3 crystal that grows. Here we report the sequences and structures of the… 
Progress of Molluscan Nacre Proteins Research
Nacre composing the inner layer of mollusk shell is a typical product of biomineralization. While main components of the organics in nacre are proteins, which mediate its distinctive lamellate
Matrix Proteins in the Outer Shells of Molluscs
TLDR
The matrix proteins identified to date from the shells of molluscs, their structural characteristics, and their roles in shell formation are reviewed.
Molecular approaches to understand biomineralization of shell nacreous layer.
TLDR
The recent research advances on nacre biomineralization of shells from bivalves and gastropods are introduced, which mainly focus on analysis of the micro- and nano-structure and components of shell nacreous layers, and investigations of the characteristics and functions of matrix proteins from nacre.
Mollusk shell formation: a source of new concepts for understanding biomineralization processes.
The biological approach to forming crystals is proving to be most surprising. Mollusks build their shells by using a hydrophobic silk gel, very acidic aspartic acid rich proteins, and apparently also
Different secretory repertoires control the biomineralization processes of prism and nacre deposition of the pearl oyster shell
TLDR
It is unambiguously demonstrate that prisms and nacre are assembled from very different protein repertoires, which suggests that these layers do not derive from each other.
Mollusk shell structures and their formation mechanism1
TLDR
The structures of mollusk shells and their process of formation are summarized, together with the analysis of various organic matrices related to shell calcification, to lead to the development of new inorganic–organic hybrid materials for various applications.
The formation and mineralization of mollusk shell.
TLDR
Today, the shell matrix appears as a whole system, which regulates protein-mineral, protein-protein, and epithelium-Mineral interactions, and these aspects should be taken in account for the future models of shell formation.
Acidic Shell Proteins of the Mediterranean Fan Mussel Pinna nobilis.
TLDR
It is shown that extremely acidic intracrystalline proteins such as caspartin interact with calcium carbonate at different scales, from micrometric to crystal lattice levels.
