The Human Protein Atlas is a histology and immunofluorescence tissue based human proteomics database, containing both normal and cancerous human tissue samples. This database can be used to determine the abundance of a protein of interest, as well as it’s location on both the tissue and cellular level.  It contains information on relative protein abundance in different human tissues and can be used to determine the most relevant cellular environment for a protein of interest.

The yeast GFP fusion localization database contains data on the abundance and cellular localization of yeast proteins. This data can be used to populate the molecular environment of a yeast cell.

The Proteomics DB can be used to compare the relative expression of a Human protein of interest between multiple tissue types. It can be used to determine the most relevant cellular environment for a protein of interest and set context for the molecule(s) of interest.

PaxDB is a comprehensive absolute protein abundance database, which contains whole genome protein abundance information for different organisms and tissue types. A list of the most abundant proteins found in a particular organism/tissue, as well as the relative abundance of those proteins, can then be used to populate the environment of a molecular landscape and set context for the molecule(s) of interest.
