Performing Annotation

Choose Genes List Analysis Tools in the main menu.
Click Analyze a gene list. A page displays the gene lists to which you have access.
Click the gene list for which you want to perform annotation.
Click the Annotation tab. The Annotation page displays and lists the equivalent ID from five different ID types:

Official Symbol
RefSeq
MGI (Mouse Genome Informatics), RGD (Rat Genome Database), or Fly Base
UniProt (Swiss Prot)
UC Santa Cruz (University of California, Santa Cruz)

It also lists:

Genetically Modified Animal Available
QTLs
Genetic Variations
Allen Brain Atlas (if applicable)

You can:

Click the Download icon to download annotation information for the gene list.
Click any link in a cell to open the website or information page for the ID you selected. If there are multiple links in a cell, each link opens a related page.

Take a look

The Accession IDs display on the left, and the equivalent IDs for these genes from six specified resources are returned; Official gene symbol, NCBI's RefSeq, Jackson Laboratory's Mouse Genome Informatics (MGI), SwissProt's UniProt, University of California Santa Cruz, and Ensembl's TranscriptSNPView. These corresponding IDs are linked to their respective databases. When you click a link, further annotation is displayed in a new window. In addition to these links, if there are any genetically modified mice available for a particular gene, information from the database of genetically modified mice (maintained by MGI) is provided. Similarly, a link to PhenoGen eQTL data for a particular gene is also provided, if available. For mouse gene lists, a link to the Allen Brain Atlas may also be displayed for a specific gene.
