Alzforum / Protein Ontology Kick-Off Meeting

The Alzforum / Protein Ontology collaboration is a driving biological project of the NIGMS-funded Protein Ontology initiative.

Goals of the meeting

The goal of this meeting is to initiate a project to create a protein information resource that will address the needs of Alzheimer's Disease (AD) researchers in a maximally effective way. The focus of the meeting will be directed primarily towards identifying these needs through discussion with specialists in different aspects of AD research. The intended long-term outcome will take the form of elaborations and extensions of the Protein Ontology (PRO), of new applications of the ontology to annotation of AD research results, and of new PRO-based software tools to support AD research.

Date and Venue

October 4-5, 2011, Hotel Indigo, Buffalo, NY

Topics to be addressed

Protein Variants

How can we most effectively represent information pertaining to the variants associated with AD and to the relations between them; for example, what level of specificity of descriptions of variants would best address the requirements of AD researchers? In the case of APP, for example, what are the genetic variants of relevance to APP? How should the Protein Ontology deal with such variants in order to assist researchers?

Aggregates of proteins / Protein complexes

What are the different kinds of aggregates and complexes relevant to AD, how do AD researchers treat them?

We envisage two case studies in the course of the meeting, both of which will be designed to serve as guidance for Protein Ontology developers in the initial phases of the project:

1. Protein case study: Perform a detailed review of one class of proteins important to AD research, chosen to be part of the research agenda of at least one of the AD scientists, to bring all participants up to the same level of understanding about what is known. Issues to be addressed will include:

importance of recording non-protein constituents
multimerism
relations to disease hypotheses
kinds of evidence
research plan
protein knowledge queries that would aid the AD researchers
protein knowledge queries that would help others retrieve AD research results

2. Protein complex case study: In addition to the issues addressed above as these arise for protein complexes, this case study will address in addition: criteria for being a complex - what amount of stability is necessary, component stoichiometry and structure, modifications/changes to complexes and associated functional changes.
