Abstract

Smallminded (smid) encodes a new member of the cdc48p/VCP subfamily of AAA proteins in Drosophila. The gene was isolated by plasmid rescue from a GAL4 enhancer trap line which shows reporter gene expression in neuroblasts, imaginal disks and a subset of sensory neurons. Larvae homozygous for the insert arrest development as second instar larvae and die without pupating. The most obvious defect in these larvae is a significantly reduced CNS, hence the naming of the gene as smallminded. The deduced amino acid sequence of smid contains a tandem duplication of the AAA nucleotide binding domain characteristic of the cdc48p/VCP subfamily. Overall, smid shares 33% identical residues with its closest relative, yeast L0919-chrXII and 26–29% with other members of the cdc48p/VCP subfamily. The most highly conserved regions of the predicted protein structure are found in and around the nucleotide binding domains. The gene is expressed at all developmental stages.
