[BioC] GO.db query error?

I suspect that you are not doing anything wrong. GO changes
frequently. And this term is simply not present in the GO package that
is online right now. The GO.db package is a snapshot of GO that matches
the GO to gene mappings from the other .db packages that were also made
at the same time. So to update it, I actually have to update all of the
packages so that everything will be in sync. And we actually do this at
least twice a year (with each release of Bioconductor). Amigo is a web
based platform and so that should usually be more current. Whether or
not that is an improvement over what we do depends on whether you want
to place more emphasis on reproducibility or accuracy.
