The ever booming field of science at present is proteomics, which deals with the identification of proteins, its structure, function and characterization. A single gene can produce multiple variants of proteins with the process involved like alternative splicing or post-translational modifications. Thus with the study of proteins have added advantage in the field of biology to understand the disease, its way to treat and to understand the cellular processes. Proteomics study is not limited to humans, the proteome of plant, animals and microbes are also now studied. The study of proteome of plants has helped to know the underlying mechanism of plantâ€s flowering, plant hormone etc.
