Hey, I have been using Gene Ontology to try to understand some differently express gene and I am now wondering if I should trust the GO annotation.
I was looking at serpinb2, for this gene I am getting GO term: GO:0005576 'extracellular region' and GO:0005615 'extracellular space'. However when I cross reference with Protein atlas, which have antibodies staining assays, then it seems to be clearly inside the cell around the golgi apparatus.
I have been trying to get the reference of those go annotation without success. Therefore which one should be trust, annotation or antibodies staining ?
