Cloning of the Drosophila prospero gene and its expression in ganglion mother cells

Biochem Biophys Res Commun. 1992 Feb 14;182(3):1326-32. doi: 10.1016/0006-291x(92)91878-t.


The Drosophila central nervous system comprises an enormous diversity of neurons that are originated from neuronal stem cells, neuroblasts. They generate a specific series of ganglion mother cells, each of which is once cleaved into a pair of neurons. Among genes known to control neurogenesis, prospero (pros) was recently identified as a gene required for gene expression specifying properties of some identified neurons. Here we report that pros encodes a nuclear protein containing a homeodomain-like sequence. In neuronal lineages of the central nervous system, pros protein is specifically detected in ganglion mother cells, although their parental neuroblasts have begun expressing a significant level of pros transcripts, suggesting a post-transcriptional control of pros expression. Our results provoke that in neuronal cell differentiation ganglion mother cells might play a pivotal role associating with the pros function.
