allergene annotation

Yes, a new term would work much better.  However, it may or may not be 
the "normal " function or process.
A virus or symbiont host interaction is a bit different, because those 
interactions are most likely critical for the life cycle (eg, if you 
don't have a host, the virus can't replicate, etc.).  Many people are 
allergic to gluten, but is that a normal function/process of  gluten?
