Table 2. Selected GO evidence codes:

These codes indicate from which source the annotation was derived. From the top to IEP, these are the experimental (EXP) evidence codes annotated manually from published experiments. IC and codes such as ISO are also annotated by curators. IBA is a manual code added by expert curators using a specialized tool, see text. A complete list of evidence codes is available.

IDA - Inferred from Direct Assay

IMP - Inferred from Mutant Phenotype

IGI - Inferred from Genetic Interaction

IPI - Inferred from Physical Interaction

IEP - Inferred from Expression Pattern

IC - Inferred by Curator

ISO - Inferred by Sequence Orthology

IBA - Inferred from Biological aspect of Ancestor

IEA - Inferred from Electronic Annotation

ND - Inferred No biological Data available
