These assignments are made based on various protein features, where one is the presence of identifiable domains. The relationship between protein domain content and function is important to investigate, to understand how domain combinations encode complex functions.<\/jats:p>\n                  <jats:p>Results: Two different models are presented on how protein domain combinations yield specific functions: one rule-based and one probabilistic. We demonstrate how these are useful for Gene Ontology annotation transfer. The first is an intuitive generalization of the Pfam2GO mapping, and detects cases of strict functional implications of sets of domains. The second uses a probabilistic model to represent the relationship between domain content and annotation terms, and was found to be better suited for incomplete training sets. We implemented these models as predictors of Gene Ontology functional annotation terms. Both predictors were more accurate than conventional best BLAST-hit annotation transfer and more sensitive than a single-domain model on a large-scale dataset. We present a number of cases where combinations of Pfam-A protein domains predict functional terms that do not follow from the individual domains.<\/jats:p>\n                  <jats:p>Availability: Scripts and documentation are available for download at http:\/\/sonnhammer.sbc.su.se\/multipfam2go_source_docs.tar<\/jats:p>\n                  <jats:p>Contact: \u00a0Kristoffer.Forslund@sbc.su.se<\/jats:p>\n                  <jats:p>Supplementary information: \u00a0Supplementary data are available at Bioinformatics online.<\/jats:p>","DOI":"10.1093\/bioinformatics\/btn312","type":"journal-article","created":{"date-parts":[[2008,6,30]],"date-time":"2008-06-30T20:13:23Z","timestamp":1214856803000},"page":"1681-1687","source":"Crossref","is-referenced-by-count":87,"title":["Predicting protein function from domain content"],"prefix":"10.1093","volume":"24","author":[{"given":"Kristoffer","family":"Forslund","sequence":"first","affiliation":[{"name":"1 Stockholm Bioinformatics Centre, Stockholm University, 10691 Stockholm, Sweden"}]},{"given":"Erik L.
