The aim of the Cardiovascular GO Annotation Initiative (BHF-UCL, British Heart Foundation – University College London) is to provide GO annotation to human cardiovascular-associated genes.  This project represents a successful collaboration between University College London (UCL) and the European Bioinformatics Institute (EBI); the annotations created by the UCL-based curators are made directly into the GOA database at the EBI.  4000 human genes have been identified as associated with cardiovascular processes and annotation priorities are agreed on an annual basis in consultation with the Co-Grant holders, the International Scientific Advisory Committee and the UCL-based GO curators.  The Initiative aims to comprehensively annotate 1500 genes in 5 years. BHF-UCL has been a GOC member since July 2008.

BHF-UCL Summary, 2009

Overview

The aim of the Cardiovascular GO Annotation Initiative (BHF-UCL, British Heart Foundation – University College London) is to provide GO annotation to human cardiovascular-associated genes. This project represents a successful collaboration between University College London (UCL) and the European Bioinformatics Institute (EBI); the annotations created by the UCL-based curators are made directly into the GOA database at the EBI. 4000 human genes have been identified as associated with cardiovascular processes and annotation priorities are agreed on an annual basis in consultation with the Co-Grant holders, the International Scientific Advisory Committee and the UCL-based GO curators. The Initiative aims to comprehensively annotate 1500 genes in 5 years. BHF-UCL has been a GOC member since July 2008.

Annotation Progress

The annotation progress reflects the priority of this project to annotate human genes, with 5710 GO terms associated to 882 human proteins (1st November 2007 to 20th November 2009). Across all species BHF-UCL have annotated 1,439 proteins with almost 11,000 GO terms.

Methods and strategies for annotation

Ontology Development Contributions

Varsha organized a heart development ontology workshop at UCL, in September 2009, which led to the creation of 250 new heart development GO terms.

In addition, since 18/09/08 the BHF-UCL team have made 246 Source Forge request (to 09/12/09), which have led to the creation of 323 new GO terms. The majority of these requests were relevant to cardiovascular processes, for example heart septum morphogenesis, aorta smooth muscle tissue morphogenesis, sarcoplasmic reticulum calcium ion transport, lipoprotein receptor binding, triglyceride homeostasis, beta-catenin-TCF7L2 complex, detection of hypoxia, thrombin receptor signaling pathway and cholesterol import. Varsha’s review of SMAD signalling pathways has led to a discussion about revising the TGF-beta signalling, BMP signalling and SMAD signalling ontologies.

Annotation Outreach and User Advocacy Efforts

The BHF-UCL GO curators are closely associated with the Cardiovascular Genetics group at UCL and have given 6 presentations at their group meetings.

Other Highlights

This year the Initiative has circulated four newsletters, in January, April, July, and October by direct email to the International Advisory Committee and individuals who have expressed an interest in this project; by indirect email, though the mailing lists of several cardiovascular related societies, as hardcopies at meetings and through our web site. In March, Ruth and Varsha attended the London Hypertension Society and London Vascular Biology Forum and distributed leaflets describing the Cardiovascular GO Annotation Initiative project.
