Default Gene Ontology in non-model organisms

I have a list of differentially expressed genes from an RNA-Seq experiment in Xenopus laevis that I'm looking to functionally annotate with GO-terms. As X.laevis is not listed in DAVID it seems I have 2 options:

- BLAST my DE genes against a database with GO terms (human/mouse) to look for orthologs
- Use a program that assigns GO from BLAST results, such as Blast2GO

I've been trying with Blast2GO recently, but find if very slow and generally lacking - does anyone have any experience doing GO in Xenopus or other non-model organisms?

I also tried Blast2Go without success using a non-model organism. After countless hours I gave up, since it was messing up my blast results IDs and at the end it was not even retrieving GO terms properly.

Finally, I did the annotation with Trinotate and it went very smoothly. The steps are well described on the website. You need blast results as an input.

Good luck with your analyses.

Default InterProScan followed by BiNGO

blast2go is on the verge of getting commercialized (as they have started selling PRO versions) and my previous experience was not so good with it. I used IntrProScan to associate GO terms with the transcript sequences. It was a long run but it also reported all the possible sequence features.

To use these custom annotation was tricky for visualization, but thanks to BiNGO, I was able to do it flawlessly. For future use I have documented it here,
