Class: gene to gene association
abstract parent class for different kinds of gene-gene or gene product to gene product relationships. Includes homology and interaction.
- is_a: Association - A typed association between two entities, supported by evidence
- GeneToGeneHomologyAssociation - A homology association between two genes. May be orthology (in which case the species of subject and object should differ) or paralogy (in which case the species may be the same)
- PairwiseGeneToGeneInteraction - An interaction between two genes or two gene products. May be physical (e.g. protein binding) or genetic (between genes). May be symmetric (e.g. protein interaction) or directed (e.g. phosphorylation)
