How do I find the promoter (driver) that I am looking for if it is not on the selection list?
Overview
You can use the tools listed under "Access Data" to find transgenes that express recombinase.
Find Recombinases-Carrying Alleles

On most MGI pages, you can access the Recombinase (cre) Activity page from the Search menu as shown in the image at right.

You can also access the recombinase portal by clicking the hyperlinked Recombinase (cre) header or icon on MGI's home page.

For this tutorial, open the Recombinase (cre) Activity page in a new window. Scroll down this page for further instructions. The "Find Recombinase-Carrying Alleles" section allows you to search for recombinase expression in a specified tissue or under the control of a given gene.

Example 1. Finding a transgene expressing recombinase under the control of HSA.
  1. Note that HSA is not listed on the Recombinase driven by selection list. Either HSA is not an approved symbol, or there are no recombinase-expressing transgenes that use this gene as a driver.
  2. Click the link to the Phenotypes, Alleles & Disease Models Query. This allows searching of synonyms.
Recombinase driven by
  1. Enter hsa in the Gene/Marker field as shown in the image on the right.
  2. Check the box next to Transgenic (Cre/Flp).
  3. Click Search.
Allele Query Form
  1. Note that several cre-expressing transgenes are listed that have ACTA1 as a promoter. ACTA1 is the approved symbol for the gene; HSA is a synonym.

    Clicking on the hyperlinked allele name in the first column will bring you to the Transgene Detail page which contains information about cre activity distribution across tissues and organ systems, models which have made use of this transgene, and transgene genetic information.
