Proteins are the products of genes and are involved in nearly every task in the body – from shaping cells to defending the body against pathogens. Proteome describes the entire set of proteins expressed by a cell, a tissue or an organism at a given time.

An altered protein, produced by a mutation in its gene, can be at the heart of diseases such as cystic fibrosis or Creutzfeldt-Jakob disease. Bioinformatics tools allow understanding how proteins exercise their role.
