Subject: Re: sun (stunted) gene Dear Leyla, Stunted is the Drosophila ATP synthase epsilon subunit and corresponds to CG9032. We have a DNA change supporting this, and also have phenotypic analysis. The maternal effect leads to abnormalities which are most apparent in the cortical embryonic divisions. The zygotic effect is that the first instar larvae grow very slowly and survive for a number of days before dying. A manuscript prepared jointly between the Ish-Horowicz and the Sullivan labs, and co-ordinated by myself and Robin Abu-Shumays is to be submitted very soon. Incidentally, the gene we initially thought was stunted is UBL3, a Drosophila homologue of HCG genes and is annotated as such - I include this in case you have access to my original personal communication to Flybase.
