[Annotation] filtering IEA translations?

We get our IEAs based on ip2go from domains contained in SwissProt 
records. However, we make sure we only use the curated records and not 
Trembl records. These appear to often contain domains that are kind of 
weird. For example, there is an S6 kinase domain that often appears, and 
then this results in getting ip2GO for ribosome, etc. for proteins that 
aren't ribosomal.
How are you getting the domain assignments?
