Of 1200 mutant chromosome arms of 2L screened, two interesting genes were identified and their functions in MB neuron development were further characterized. These two genes are Cul3 and Chinmo. Cul3 encodes a scaffold protein for E3 ubiquitin ligase. Phenotypic analysis demonstrates that Cul3 is required for proper axon arborization and dendritic elaboration of MB neurons. Chinmo is a novel BTB-zinc finger protein. Functional analysis shows that Chinmo is an important intrinsic factor involved in birth order-dependent specification of neuronal identities.
