Proteomics

Proteomics is a branch of molecular biology that deals with the identification and quantification proteins in living objects, as well analysis protein functions their interactions.
 studied by are expressed given cell, tissue or organism over period time (under certain conditions).
 It known information about primary structure (the sequence amino acid residues protein) contained structural gene form codon (genetic code). On other hand, less than 10% genes functionally active (expressed) somatic cells our body. Moreover, distinct tissue-specific expression observed. This, turn, leads to peculiarities qualitative composition synthesized various tissues. No important fact total amount tissues much greater number containing original structure. This phenomenon explained activity such mechanisms alternative splicing wide variety post-translational peptide processing pathways (covalent modification polypeptide on ribosome) health disease. Thus, even brief review semantic content term "proteomics" indicates an extremely complex system molecules body, which plays fundamental role maintaining homeostasis involved formation adaptive responses response adverse changes internal external environment.
