As a newbie, I am interested to know the rationale of doing proteomics work. As many of us know that "proteome analysis is required to determine which proteins have been conditionally expressed, how strongly, and whether any posttranslational modifications are affected". (between health and diseased tissue i.e., human or plant tissue)
What is the next step, If I know a protein that is expressed in response to biotic and abiotic factors? Is it only useful for writing a papers? or How can this results be useful?
