Item Protein Ontology (PRO): enhancing and scaling up the representation of protein entities(Oxford University Press, 2016-11-28) Natale, Darren A.; Arighi, Cecilia N.; Blake, Judith A.; Bona, Jonathan; Chen, Chuming; Chen, Sheng-Chih; Christie, Karen R.; Cowart, Julie; D’Eustachio, Peter; Diehl, Alexander D.; Drabkin, Harold J.; Duncan, William D.; Huang, Hongzhan; Ren, Jia; Ross, Karen; Ruttenberg, Alan; Shamovsky, Veronica; Smith, Barry; Wang, Qinghua; Zhang, Jian; El-Sayed, Abdelrahman; Wu, Cathy H.; Darren A.

Wu; Arighi, Cecilia N.; Chen, Chuming; Chen, Sheng-Chih; Cowart, Julie; Huang, Hongzhan; Ren, Jia; Wang, Qinghua; Wu, Cathy H.The Protein Ontology (PRO; http://purl.obolibrary. org/obo/pr) formally defines and describes taxonspecific and taxon-neutral protein-related entities in three major areas: proteins related by evolution; proteins produced from a given gene; and proteincontaining complexes. PRO thus serves as a tool for referencing protein entities at any level of specificity. To enhance this ability, and to facilitate the comparison of such entities described in different resources, we developed a standardized representation of proteoforms using UniProtKB as a sequence reference and PSI-MOD as a post-translationalmodification reference. We illustrate its use in facilitating an alignment between PRO and Reactome protein entities. We also address issues of scalability, describing our first steps into the use of text mining to identify protein-related entities, the large-scale import of proteoform information from expert curated resources, and our ability to dynamically generate PRO terms. Web views for individual terms are now more informative about closely-related terms, including for example an interactive multiple sequence alignment. Finally, we describe recent improvement in semantic utility, with PRO now represented in OWL and as a SPARQL endpoint. These developments will further support the anticipated growth of PRO and facilitate discoverability of and allow aggregation of data relating to protein entities.Item Toll-Like Receptor Signaling in Vertebrates: Testing the Integration of Protein, Complex, and Pathway Data in the Protein Ontology Framework(Public Library of Science (PLOS), 2015-04-20) Arighi, Cecilia N.; Shamovsky, Veronica; Masci, Anna Maria; Ruttenberg, Alan; Smith, Barry; Natale, Darren A.; Wu, Cathy H.; D’Eustachio, Peter; Cecilia Arighi, Veronica Shamovsky, Anna Maria Masci, Alan Ruttenberg, Barry Smith, Darren A. Natale, Cathy Wu, Peter D’Eustachio; Arighi, Cecilia; Wu, CathyThe Protein Ontology (PRO) provides terms for and supports annotation of species-specific protein complexes in an ontology framework that relates them both to their components and to species-independent families of complexes. Comprehensive curation of experimentally known forms and annotations thereof is expected to expose discrepancies, differences, and gaps in our knowledge. We have annotated the early events of innate immune signaling mediated by Toll-Like Receptor 3 and 4 complexes in human, mouse, and chicken. The resulting ontology and annotation data set has allowed us to identify species-specific gaps in experimental data and possible functional differences between species, and to employ inferred structural and functional relationships to suggest plausible resolutions of these discrepancies and gaps.
