Gd. Bader et Cwv. Hogue, BIND - a data specification for storing and describing biomolecular interactions, molecular complexes and pathways, BIOINFORMAT, 16(5), 2000, pp. 465-477
Motivation: Proteomics is gearing up towards high-throughput methods for id
entifying and characterizing all of the proteins, protein domains and prote
in interactions in a cell and will eventually create more recorded biologic
al information than Human Genome Project. Each protein expressed in a cell
can interact with various other proteins and molecules in the course of its
function. A standard data specification is required that can describe and
store this information in all its detail and allow efficient cross-platform
transfer of data. A complete specification must be the basis for any datab
ase or tool for managing and analysing this information.
Results: We have defined a complete data specification in ASN.1 that can de
scribe information about biomolecular interactions, complexes and pathways.
Our group is using this data specification in our database, the Biomolecul
ar Interaction Network Database (BIND). An interaction record is based on t
he interaction between two objects. An object can be a protein, DNA, RNA, l
igand, molecular or an interaction. Interaction description encompasses cel
lular location experimental conditions used to observe the interaction, con
served sequence, molecular location, chemical action, kinetics, thermodynam
ics, and chemical state. Molecular complexes are defined as collections of
more than two interactions that form a complex, with extra descriptive info
rmation such as complex topology. Pathways are defined as collections of mo
re than two interactions that forma pathway, with additional descriptive in
formation such as cell cycle stage. A request for proposal of a human reada
ble flat-file format that mirrors the BIND data specification is also tende
red for interested parties.

lecular complex and pathway data is available at ftp://bioinfo.mshri.on.ca/
