How do I find existing recombinase-expressing transgenes/knock-ins that have a given promoter (driver)?
Find Recombinase-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.

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