PPLRE OrganismProteinLocalization Table

• The PPLRE OrganismProteinLocalization Table is a PPLRE Table that will contain the both the curated OPL() relations, and the relations predicted by PPLRE.

Metadata

Attribute Name	Description
PPLID	An integer that identifies a unique localization of an organism’s protein. The primary key of the table. (i.e. multiple localizations for a protein will have multiple entries).
OrganismID	An identifier to the organism in the relationship. A foreign key to the Organism. (n.b. the NCBI taxonomy id)
ProteinID	An identifier to the protein in the relationship. A foreign key to the Protein table.
LocalizationID	A foreign key to the Localization table that identifies the localization region in the relationship.
PassageID	A foreign key to the DocumentParagraph table. The value identifies the region of text that contains the suggestion of the relationship.
MethodUsed	Denotes whether the relationship is an experimental discovery (i.e. in a published article), or is a suggested relationship due to similarity to another protein (BLAST homology), or predicted (by PSORT-b or PA-SUB). Valid values: “Experiment, Similarity, Other”. For the first phase of the project this will likely contain only examples of “Experiment”.
Likelihood	A number that indicates the expected truth of a predicted relationship. Valid values: [1.0-true, 0.0-false]. Has value 1.0 for records where MethodUsed=Experimental.
