Shell matrix proteins

Eggshell formation takes place in the shell gland of the oviduct of laying hens. The eggshell is rich in calcium and various glycoproteins synthesised in the shell gland. Although studies have identified genes involved in eggshell formation, little is known about the regulation of genes in the shell gland particularly in a temporal manner.

Biomineralization by molluscs involves regulated deposition of calcium carbonate crystals within a protein framework to produce complex biocomposite structures. Effective biomineralization is a key trait for aquaculture, and animal resilience under future climate change.

We found a novel 52 kDa matrix glycoprotein MPP1 in the shell ofCras-sostrea nippona that was unusually acidic and heavily phosphorylated. Deduced from the nucleotide sequence of 1.9 kb cDNA, which is likely to encode MPP1 with high probability, the primary structure of this protein shows a modular structure characterized by repeat sequences rich in Asp, Ser and Gly.

The nucleocapsid complex is surrounded by a protein shell called capsid to form the viral core. A layer of matrix protein, which is formed outside the capsid, interacts with the envelope (env) which consists of lipid envelope derived from the host cell and viral envelope glycoproteins. Viral glycoproteins are made of two units: a transmembrane portion, which attaches the protein into the lipid bilayer, and a surface portion, which binds to the cellular receptor.
