Confirming predicted gene model by RNA-Seq data
Dear Everyone,
I am just wondering if we have any available tool to automatically confirm that a predicted gene model is correct or not based on RNA-Seq data? The only way to examine a gene model that I know is to visually compare the gene model and the RNA-read coverage on GBrowse. However, this method is time-consuming. If I have thousands of proteins which are candidates to be selected for further cloning, expression and biochemically characterization steps, and I have RNA-Seq read data of the genes encoding these proteins, could you please tell me how I can quickly know which proteins have correct gene models? Any ideas from you will be much highly appreciated.
Kindly regards,
Minh Nguyen

You could take all your gene sequences and use your local NCBI Blastx program. In the command line, just note that you only want the top blast result.

Can you upvote or confirm that either of these processes worked for you please.

Could a "complete" RNA-Seq database feasibly exclude some protein-coding transcripts?
written by Kristin Muench
What kind of information (of the predicted models) that you have currently: genomic coordinates, protein sequence, or? Honestly I don't really get your point on what to confirm by RNA-seq, protein or gene model? It's a bit of a more complex task (it's another story), since protein levels are not necessarily correlating with (supposedly corresponding) RNA levels.
Thank you for your reply! I have protein and CDs sequences. I need to check if the corresponding predicted gene models of these protein/CDs sequences are correct or not. The RNA-Seq read data is used to check the gene models.
Use a BLASTP program, then TBLASTX to confirm with your RNAsequences.
Thanks for your suggestion!
