Ontology Meeting, Palo Alto, Jan 10 & 11, 1999 Participants: SCD and Arabidopsis Databases Mike Cherry, David Botstein, curators of SCD and Arabidopsis db. =46lyBase Michael Ashburner & Suzi Lewis MGD Janan Eppig, Joel Richardson, Judith Blake Astra Ken Fasman 1. One or three? Answer is Three: The first discussion reaffirmed that the Ontologies will be developed independently. In the future, we may explore edges between the independent ontologies, but not now. After stabilization and initial annotations of product to list terms, we will see whether to combine all together, what the levels of annotation are by species, and see about establishing edges between the three sets of terms. - don't get into describing 'location' as part of 'function' - three ontologies are a) function b) process c) subcellular location (but see below). 2. Gene Function vs. Gene Products? Recognized confusion in gene product/complex listings in function list. Agreed to move protein complexes and their components to the 'cellular' list. Renamed 'cellular location' to 'cellular components'. Decided not to create a fourth category, but rather to think of 'cellular' syntax as 'is located in' with synonym 'is subcomponent of'. Recognized a subtle distinction between something that is 'part of' a macromolecule and something that is 'located in' i.e. 'part of' the nucleus. Still, decided all would be placed in this category. This is a system designed to deal with a state of incomplete knowledge. Cell is composed of the whole set of product complexes. 3. Define syntax: a. function=8A 'is a' , hierarchical=8A b. process=8A'is a subprocess of' but may also list 'is an instance of', a DAG c. component=8A'is located in' synonym: 'is subcomponent of' but may also list 'is an instance of', a DAG. 4. Specific function syntax=8A a) Not for =8A Drop the 'Not for Mus, Not for Drosophila' distinctions b) Precursors =8A receive function process annotation of mature protein. c) Facultative/Obligatory=8A'maybe part of', 'sometimes part of', 'part of >>under certain conditions' some things present at sometimes, not at others= , or don't know. Some things spend some of the time in one compartment and some in the other (cell cycle proteins). Decide not to annotate these distinctions. Decide function ontology will be a straight 'is a', no qualifiers. 5) Cell is a generic cell, will not divide by cell type. Generic gene products will be listed as needed. example: Alpha tubulin=8A.yeast has two, elegans has 6, some are there in mitosis, some are not. what are leaves of the trees? are they nodes representing genes from all species? So, we've thrown out individual gene products except as needed, but gene complexes still here. Not creating laundry list of gene products of each species, but adding component parts as necessary. Example 1. a) cellular component: gene product A, gene product B, gene product C b) function: alpha tubulin c) process: mitosis, axonal transport Not going to put in the relatedness between complex, process, and function until we have some data and a better understanding of how this will work. 6) If you have process, function and localization, it's almost as good as having a small paragraph about the gene. (example of micro-array paper) 7) Implementation Plan a) Michael does revision of current version b) All participants edit list very carefully c) Suzi assigns GO numbers 'for real' d) Start alpha annotations e) Future terms added through 'ontology manager', currently Michael. 8) Immediate future a) requires prototype funding (possibly from Astra via Ken Fasman, other ideas too) b) each database needs one curator for project c) need overall curation manager (currently Michael, person would work with Michael) d) each database needs capitol money for computer 'kit' e) need money for meetings/travel. two meetings/year, alternate coasts f) need programmer, ultimately 2, one for database DBA, when db created, second for interface, tools. Astra is buying our commitment to annotate our databases to the common vocabulary=8Alooking for increased usability and searchability of each individually and collectively.
