Proteomics

Proteomics

A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Background:

Biomineralization is a biologically controlled process forming hard tissues like skeletons and teeth in animals.
Biominerals in invertebrates are crucial for evolutionary success, exhibiting hierarchical composite structures with superior mechanical properties.
Proteins, though a small fraction (~5 wt%) of biominerals, play vital roles in their formation.

Purpose of the Study:

To review biomineral proteomics in invertebrate animals.
To highlight the diversity of biomineral proteins and their functions.
To explore the applications of biomineral proteomics in various scientific fields.

Main Methods:

Analysis of accumulating biomineral protein data using high-throughput methods like proteomics.
Comparison of proteomes across different species and biomineral types.
Identification of common protein domains and species-specific domains.

Main Results:

Biomineralization involves thermodynamic crystal growth alongside extracellular matrix activity and/or vesicle transport.
Biominerals possess functions related to biological immunity and antipathogen activity.
Von Willebrand factor type A and epidermal growth factor domains are frequently identified; species-specific domains aid in predicting biomineral types.

Conclusions:

Biomineral proteomics provides insights into the complexity of biomineral formation.
Shell matrix proteins can be used to predict biomineral types.
Biomineral proteomics has broad applications in fields such as tissue regeneration, developmental biology, archeology, environmental science, and material science.
