proteome

The term proteome refers to an organism’s collection of proteins. A cellular proteome is the collection of proteins found in the particular cell type under a particular set of environmental conditions. The complete proteome for an organism is the potential complete set of proteins, and equates to the sum of cellular proteomes under all possible conditions. The term, introduced in 1995, is analogous to the term genome for nucleic acids, though the proteins themselves are coded for by a portion of the genome.
