This page displays GO annotations in different sections according to the annotation method used to add that annotation to SGD.

* Manually curated GO annotations reflect our best understanding of the basic molecular function, biological process, and cellular component for this gene product. Manually curated annotations are assigned by SGD curators based on published papers when available, or by curatorial statements if necessary. Curators periodically review all Manually curated GO annotations for accuracy and completeness. The "Last Reviewed on:" date at the top of this section indicates when these annotations were last reviewed.

** GO annotations from High-throughput experiments are made based on a variety of large scale high-throughput experiments, including genome-wide experiments. Many of these annotations are made based on GO annotations (or mappings to GO annotations) assigned by the authors, rather than SGD curators. While SGD curators read these publications and often work closely with authors to incorporate the information, each individual annotation may not necessarily be reviewed by a curator. GO Annotations from high-throughput experiments will be assigned only when this type of data is available, and thus may not be assigned in all three aspects of the Gene Ontologies.

Biological Process

Computational Biological Process
Annotation(s)	Evidence	Reference(s)	Assigned By
cell cycle	IEA: Inferred from Electronic Annotation with EBI:KW-0131 Last updated 2013-03-02	UniProt-GOA  (2011) Gene Ontology annotation based on manual assignment of UniProtKB keywords in UniProtKB/Swiss-Prot entries.	UniProtKB

*** Computational GO Annotations are predictions. These annotations are NOT reviewed by a curator. Currently, all computational GO annotations for S. cerevisiae are assigned by an external source (for example, the Gene Ontology Annotation (GOA) project of the European Bioinformatics Institute (EBI)).
