Drosophila morgue influences cell numbers and positions in the embryonic nervous system.

Morgue is a unique multi-domain protein that contains a zinc finger motif, an F box, and a variant E2 conjugase domain. The presence of these domains suggests potentially complex and novel functions for Morgue in ubiquitination pathways. Morgue was originally identified via its gain-of-function enhancement of eye cell death phenotypes in Drosophila and ectopic expression of Morgue also influences circadian rhythms.
