Gene attributes that don't fit into process, component and fu nction ontologies?

Hi Michael,

While the ontology at http://www.cbil.upenn.edu/Ontology/MGED_ontology.html 
looks at first glance to be an excellent ontology to describe tissue and 
cell samples and describe the microarray (and potentially other) 
experiments performed on them, it doesn't really address biochemical and 
genetic attributes of genes and gene products that are excluded from 
process, function and component as in the examples I gave earlier.  I am 
really not sure how to break this down into separate ontologies, but as a 
start maybe: intrinsic properties, regulation, modifications, interactions 
(see a rough example below).

We certainly wouldn't want to duplicate the SwissProt effort, but are they 
developing an ontology, or a flat set of controlled-vocabulary terms?  One 
might consider developing an ontology with the same format and using the 
same tools as GO, and then map annotation from Swiss-Prot keywords to this 
ontology?

Rough attempt at example ontology extensions:

% intrinsic properties
  % contains intron(s)
   % differentially spliced
  % codon usage
  % domain family homology
   %PFAM

% regulation
  % transcriptional
    % induced
     % enhanced
  % repressed
   % silenced
  % post-transcriptional
   % regulated degradation
  % regulated translation

% modifications
  % DNA level
   % methylation
  % transcript level
   % methyl G capped
  % protein level
   % myristoylated

% interactions (excluding protein complexes already covered in component 
ontology)
  % DNA level
  % RNA level
  % protein level
