proteomics

noun

1. (uncountable)The branch of molecular biology that studies the set of proteins expressed by the genome of an organism.

   “The derived word "proteomics", which has come into use almost as an afterthought, may be equally useful since it indicates something less well-defined but more ambitious. Proteomics is a field, just as genomics is, rather than a closed and conceptually static body of knowledge (as are the genome and proteome, by definition).”
