A gene is a localized section of DNA; through a process called transcription this DNA is copied into a messenger RNA (mRNA). The mRNA is a copy of the gene DNA sequence; mRNA is later translated to a protein through a process called translation. After the translation the protein needs the addition or removal of some elements in order to become active and perform its correct function, these are called post-translational modifications. A protein is conformed by a sequence of aminoacides, these modifications are made on specific aminoacids on the proteins.
BioGRID interactions are recorded as relationships between two proteins or genes (i.e. they are binary relationships) with an evidence code that supports the interaction and a publication reference. The term “interaction” includes, as well as direct physical binding of two proteins, co-existence in a stable complex and genetic interaction. It should not be assumed that the interaction reported in BioGRID is direct and physical in nature; the experimental system definitions below indicate the nature of the supporting evidence for an interaction between the two biological entities. It should also be noted that some interactions in BioGRID have various levels of evidential support. BioGRID simply curates the result of the experiment from the publication and does not guarantee that any individual interaction is true, well-established or the current consensus view of the community. Curating all available evidence supporting for an interaction enables orthogonal data from various sources to be collated, allowing users of the database to decide confidence in the existence and/or physiological relevance of that interaction.
The Biological General Repository for Interaction Datasets (BioGRID) is a public database that archives and disseminates genetic and protein interaction data from model organisms and humans (thebiogrid.org). BioGRID currently holds over 980,000 interactions curated from both high-throughput datasets and individual focused studies, as derived from over 55,000 publications in the primary literature. Complete coverage of the entire literature is maintained for budding yeast (S. cerevisiae), fission yeast (S. pombe) and thale cress (A. thaliana), and efforts to expand curation across multiple metazoan species are underway. Current curation drives are focused on particular areas of biology to enable insights into conserved networks and pathways that are relevant to human health. BioGRID provides interaction data from several model organism databases, resources such as Entrez-Gene, SGD, TAIR, FlyBase and other interaction meta-databases.
