We previously identified ashwin, a novel highly conserved gene, in a differential display screen for genes expressed at initial stages of neural specification. Ashwin is a transcriptional repressor, and overexpression of ashwin leads to a puzzling combination of phenotypes, including both double-axis, or twinned, embryos, and embryos with anterior truncations. Our working hypothesis is that both phenotypes result from localized inhibition of the anterior organizer, although ashwin apparently has multiple targets at different developmental stages. Loss-of-function studies suggest that ashwin regulates cell survival, and it may also be required for the establishment of posterior pattern. We are currently investigating the mechanisms of ashwin action and its role in early development.
