Editing Proteome (section)

== Protein databases ==
The [https://www.proteinatlas.org/ Human Protein Atlas] contains information about the human proteins in cells, tissues, and organs. All the data in the knowledge resource is open access to allow scientists both in academia and industry to freely access the data for exploration of the human proteome. The organization [https://elixir-europe.org ELIXIR] has selected the protein atlas as a core resource due to its fundamental importance for a wider life science community.

The [http://www.plasmaproteomedatabase.org Plasma Proteome database] {{Webarchive|url=https://web.archive.org/web/20210127090529/http://www.plasmaproteomedatabase.org/ |date=2021-01-27 }} contains information on 10,500 [[blood plasma]] proteins. Because the range in protein contents in plasma is very large, it is difficult to detect proteins that tend to be scarce when compared to abundant proteins. This is an analytical limit that may possibly be a barrier for the detections of proteins with ultra low concentrations.<ref name="Ponomarenko">{{Cite journal|last1=Ponomarenko|first1=Elena A.|last2=Poverennaya|first2=Ekaterina V.|last3=Ilgisonis|first3=Ekaterina V.|last4=Pyatnitskiy|first4=Mikhail A.|last5=Kopylov|first5=Arthur T.|last6=Zgoda|first6=Victor G.|last7=Lisitsa|first7=Andrey V.|last8=Archakov|first8=Alexander I.|date=2016|title=The Size of the Human Proteome: The Width and Depth|journal=International Journal of Analytical Chemistry|volume=2016|pages=7436849|doi=10.1155/2016/7436849|issn=1687-8760|pmc=4889822|pmid=27298622|doi-access=free}}</ref>
