TableInfo: biosample_protein.tsv

Association between a biosample and a UniProt term

For biosamples with protein metadata, this table will have one row for each protein associated with each such biosample.

All fields are required: this table can be empty (header-row only), but any non-header rows must leave no fields blank.

Some examples:

• If you don't have any biosamples associated with proteins, this table should be left empty.
• If you have exactly one protein associated with each biosample, this table will have as many rows as biosample.tsv.
• If you have five proteins associated with each biosample, this table will have five times as many rows as biosample.tsv.
• If some but not all of your biosamples are associated with one or more proteins, this table will contain one row for each protein assigned to each such biosample (and the resulting row count will not have any obvious relationship to the number of rows in biosample.tsv, which is both expected and fine in such a case).

Field	Field Description	Required?	Field Value Type	Extra Info
biosample_id_namespace	Identifier namespace for this biosample [part 1 of 3-component composite primary key]	Required	string	This will be the value of id_namespace in the row in biosample.tsv corresponding to the biosample referenced in this row. If your program has not registered multiple CFDE identifier namespaces, this will be exactly the same value for all rows.
biosample_local_id	The ID of this biosample [part 2 of 3-component composite primary key]	Required	string	This will be the value of local_id in the row in biosample.tsv corresponding to the biosample referenced in this row.
protein	A UniProt Knowledgebase (UniProtKB) protein accession (AC) [part 3 of 3-component composite primary key]	Required	string	Example: Q6GZX4
