I am just learning about Gene Ontology and I find it very useful to
modern day biologists. As I read through the introduction, I am
wondering why on the explanantions for Gene Peoducts I do not see
any mention of the word 'protein'. Is not gene product also a
protein? I can though understand the ease of confusing gene
products and molecular function. Your insights will be greatly
appreaciated.

Answer:
A gene product may be a protein or an RNA. The Gene Ontology
documentation
uses 'gene product' so that transcripts and functional RNAs, which can be
annotated using GO terms, will not appear to be excluded.

Please don't put the question in exactly as worded in the email. Instead,
I'd use 'What is a gene product?' or 'Why does GO refer to 'Gene
products?'. The answer can also be reworded, e.g. to 'A gene product is
any protein or RNA encoded by a gene.' or you can use something like
what we put in the Current Protocols chapter on GO. (Jen - i'll send you a
copy off-tracker.)
I could have sworn that the old general documentation page explained
what a gene product is, but the relevant blurb is missing now. It used to
be at the beginning of the 'Gene Products' section, and could be restored
to the same place.

I've added a new FAQ for this.
