The Gene Ontology Consortium's Community Annotation wikis allow members of the scientific community to review GO annotation for their genes of interest across several species and provide us with additional information to guide our annotation efforts for these genes. MGI GO curators will act promptly on any information relevant for mouse GO curation entered in the wikis. The GO Community Annotation Wiki for Immunology contains pages for immunologically related genes and processes. The GO Community Annotation Wiki for Cardiovascular Biology contains pages for genes and processes related to cardiovascular development and physiology. The GO Community Annotation Wiki for Muscle Biology contains pages for genes related to muscle development and physiology.
