A search by homology returns protein sequences that have high-scoring alignments with the transcripts of interest. To search for homology hits
- Make sure the Find by homology to.. radio button is selected.
- Enter your search terms in the Search Terms text box. When choosing search terms for a homology search, think about the typical deflines of curated protein sequences; those are the keywords you're likely to find. You can also restrict the taxa of protein sequences which are searched (see Searching Specific Fields).
- Select whether you want to limit results by a maximum E-value or a minimum BLAST score in the Find by homology drop-down menu.
- Enter the cutoff E-value or score in the Find by homology text box. Higher scores or lower E-values yield faster searches and fewer results.
Proteins (and their parent transcripts) are returned in alignment-significant order (highest score or lowest E-Value first). The returned results include the following links:
- P Link to the Protein page for the transcript.
- T Link to the transcript annotation page. If you
are a registered annotator, you can view and enter additional information
about this transcript and protein.
- G Link to a Genome Browser-based view of this transcript.
- H Link to a Protein Alignment Report.
- No more than 10,000 hits are returned for a homology search.
