We describe a developmental analysis of Drosophila Cullin‐5 (Cul‐5) identified from the genome sequence on the basis of its high degree of homology to vertebrate and worm sequences. The gene is expressed in a restricted manner in ectodermal cells throughout development suggesting pleiotropic functions. We decided to examine the phenotypes of Cul‐5 aberrations in two well‐studied developmental systems: the neuromuscular junction (NMJ) and the developing sensory organ. Alteration of Cul‐5 levels in motoneurons results in an increase in bouton number at the NMJ. The cells of a sensory organ on the adult notum arise from a single progenitor cell by regulated cell division. Aberrations in Cul‐5 affect different steps in the lineage consistent with a role in cell fate determination, proliferation, and death. Such phenotypes highlight the multiple cellular processes in which Cul‐5 can participate. Developmental Dynamics 232:865–875, 2005. © 2005 Wiley‐Liss, Inc.
