Proteomics and Cell Culture

The term proteome references the total quantity of proteins present at any given time in a cell, tissue, or organism. The number of these proteins can vary over time and between types of cells and conditions of growth. This is because of variations in gene expression. This area of research is a quickly advancing sector in the broader field of molecular biology. Proteomics studies typically provide results in the form of protein content inventories of proteins differentially expressed throughout various conditions.

Function of Proteomics

Proteomics evaluates the actions, changes, and exchanges within protein complexes, which establishes their function. The importance of proteins within systems of cells cannot be overstated. They provide structural elements, maintain metabolic processes, and are key in regulating gene expression. They operate as signal initiators or receptors and composing the subsequent products.

A cell reacts to external and internal modifications by regulating the level and activity of its proteins. As a result, changes in the proteome reveal a picture of the activity of the cell. Study of the proteome allows for the knowledge and understanding of the operation, structure, and interactions of all of the protein content in a particular organism.

Proteomics involves various areas of study today, including protein function, protein interaction, protein localization, and protein modification. The main objective is to identify all of the proteins in a cell and produce a comprehensive 3D cell map that pinpoints their specific locations and distributions.

Including Genomics

Proteomics uses various methodologies in the study of functional genomics and disease models, including mass spectrometry, sequencing, and immunoassays. Post-translational modifications are recognized in this area of research.

Proteomics often involves a parallel line of study with genomics. Genomics begins with a gene for the purposes of making conclusions about its proteins. On the other hand proteomics starts with a protein that is functionally modified and proceeds backwards to the gene which produced it.
