Proteomics is the large-scale study of proteins, particularly their structures and functions. This term was coined to make an analogy with genomics, and while it is often viewed as the "next step", proteomics is much more complicated than genomics. Most importantly, while the genome is a rather constant entity, the proteome differs from cell to cell and is constantly changing through its biochemical interactions with the genome and the environment. One organism has radically different protein expression in different parts of its body, in different stages of its life cycle and in different environmental conditions.

The entirety of proteins in existence in an organism throughout its life cycle, or on a smaller scale the entirety of proteins found in a particular cell type under a particular type of stimulation, are referred to as the proteome of the organism or cell type respectively.

Since proteins play a central role in the life of an organism, proteomics is instrumental in discovery of biomarkers, such as markers that indicate a particular disease.

@moonhouse OK! I would love to read it, if possible? We are working with proteomics data ourselves (2-DE, MS, LC, etc.)

@olaforsstrom It was about XML formats for proteomics data. We compared what information the different format supported. Published in 2007.

@olaforsstrom Jag har fått en artikel publicerad i tidskriften Proteomics. Vad det sedan säger vet jag inte.

I do! :) RT @superaf: My gosh! Bio project's so difficult! Anybody knws anything abt genomics? Transcriptomics? Proteomics? OR Metabolomics?

@Nurhirda she my PROTEOMICS classmate last year..BLOODY ANNOYIN..but at the same time i teached her alot..i knw it somehw we talkin abt her.
