We recently udpated our Gene List Annotation for Drosophila (GLAD) online resource.  At GLAD you could already view the members of a gene list, such as genes grouped as members of a pathway, process, or sharing a functional domain. Now, you can also ask if a gene of interest is a member of a given group. Please see examples of the two ways to use GLAD below. As always, we welcome your feedback, including suggestions for changes or additions to the curated lists, or for addition of new lists.
