Applications of Proteomics:

Proteomics has broad applications in all the aspects of life sciences including several practical applications as drug development against several diseases. Difference in expression protein expression profile of normal and diseased person may be analyzed for target protein. Protein to gene may be predicted (Fig.4). Once protein/gene is identified, function may be predicted. This can help in disease management/drug development.

From Protein To Gene

Figure 4 : Proteomic analysis-protein to gene sequence

Whole genome sequences of several organisms have been completed but genomic data does not show how proteins function or how these proteins are involved in biological processes. Gene codes for a protein by at several occasion proteins are modified after synthesis (several types of post-translational modifications) for functional diversification. In the current course, we shall study several applications of proteomics in coming lectures.
