8. 8 EMBRACE Workshop 7-9 th November 2007 Core information needed for a GO annotation 1. Gene or gene product identifier e.g. Q9ARH1 2. GO term ID e.g. GO:0004674 (protein serine/threonine kinase) 3. Reference ID e.g. PubMed ID: 12374299 GO_REF:0000001 4. Evidence code e.g. IDA..and also in some cases: - Qualifiers available to modify interpretation of annotation: NOT contributes_to colocalizes_with - ‘With’ column information, to provide further information on the method (evidence code)

9. 9 EMBRACE Workshop 7-9 th November 2007 Electronic Annotation A number of different techniques used by different GO Consortium annotation groups. All resulting annotations must be high-quality and provide an explanation of the method (GO_REF) 1. Mapping of external concepts to GO terms 2. Automatic transfer of annotations to orthologs

15. 15 EMBRACE Workshop 7-9 th November 2007 Finding Annotations In this study, we report the isolation and molecular characterization of the B. napus PERK1 cDNA, that is predicted to encode a novel receptor-like kinase. We have shown that like other plant RLKs, the kinase domain of PERK1 has serine/threonine kinase activity, In addition, the location of a PERK1-GTP fusion protein to the plasma membrane supports the prediction that PERK1 is an integral membrane protein…these kinases have been implicated in early stages of wound response… wound response serine/threonine kinase activity, integral membrane protein …for B. napus PERK1 protein (Q9ARH1) PubMed ID: 12374299 FUNCTIONprotein serine/threonine kinase activityGO:0004674 COMPONENTintegral to plasma membraneGO:0005887 PROCESSresponse to woundingGO:0009611

17. 17 EMBRACE Workshop 7-9 th November 2007 Core information needed for a GO annotation 1. Gene or gene product identifier e.g. Q9ARH1 2. GO term ID e.g. GO:0004674 (protein serine/threonine kinase) 3. Reference ID e.g. PubMed ID: 12374299 GO_REF:0000001 4. Evidence code e.g. IDA..and also in some cases: - Qualifiers available to modify interpretation of annotation NOT contributes_to colocalizes_with - ‘With’ column information, to provide further information on the method (evidence code)

18. 18 EMBRACE Workshop 7-9 th November 2007 The ‘Qualifier’ Column The Qualifier column is used to modify the interpretation of an annotation. Allowable values are: NOT colocalizes_with contributes_to

19. 19 EMBRACE Workshop 7-9 th November 2007 The ‘NOT’ qualifier 'NOT' is used to make an explicit note that the gene product is not associated with the GO term. … particularly important when associating a GO term with a gene product should be avoided (but might otherwise be made, especially by an automated method). Also used to document conflicting claims in the literature. NOT can be used with ALL three GO Ontologies. e.g. This protein does not have ‘kinase activity’ because it has been found that this protein has a disrupted/missing an ‘ATP binding’ domain.

20. 20 EMBRACE Workshop 7-9 th November 2007 The ‘colocalizes_with’ qualifier Only used with GO Component Ontology Gene products that are transiently or peripherally associated with an organelle or complex may be annotated to the relevant cellular component term, using the 'colocalizes_with' qualifier.

21. 21 EMBRACE Workshop 7-9 th November 2007 The ‘contributes_to’ qualifier i.e. annotating 'to the potential of the complex‘ distinguishes an individual subunit from complex functions All gene products annotated using 'contributes_to' must also be annotated to a cellular component term representing the complex that possesses the activity. Only used with GO Function Ontology Where an individual gene product that is part of a complex can be annotated to terms that describe the action (function or process) of the whole complex.
