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.
