How to find a gene of interest in COMBREX

To find a gene of interest in the COMBREX gene database, enter information about the gene into the search field within the COMBREX homepage.

In COMBREX, information about a gene is stored within its gene detail page. In order to locate the appropriate gene detail page, search for it using the search tools on the main page. COMBREX supports searching for a gene using keywords, Entrez gene id, protein GI, RefSeq protein accession id, Uniprot id, and gene symbol.

Examples of search terms accepted for a COMBREX query:

Entrez GeneIDs are typically of the form: RefSeq protein accessions are typically of the form: Uniprot IDs are typically of the form: Gene Symbols are typically of the form: Gene Ontology GO terms are typically of the form: Enzyme Commission (EC) numbers are typically of the form: NCBI Protein Cluster accession numbers are typically of the form: and Gene names and keywords can take a variety of forms:    In general, the more specific the information used in your search, the easier it is to locate the specific gene of interest. Therefore, whenever possible, we advise that you search for a specific gene using its Entrez gene ID or protein GI. If you search using keywords, COMBREX will in most cases return multiple protein clusters. You must then go through each protein cluster page until you find the appropriate gene link. Once you have located this link, clicking on it will bring you to the appropriate gene page.

The advanced search functionality can be used to specify your query and consequently limit your search results, allowing you to more easily find your gene of interest. Advanced search can be used to specify the organism, the experimental validation status of the gene, and/or the experimental validation status of the cluster. Advanced search can also be used to restrict your search to genes with predictions submitted to COMBREX, genes containing a Pfam domain also found in human genes, genes with structure entries in RCSB Protein Data Bank, genes with predictions of function submitted to COMBREX, and more.
