Description

A duplicated sev enhancer and Hsp70 promoter drive expression of a mutated dos cDNA; all Tyr residues outside the DOS PH domain except Y801 and Y854 have either been removed by deletion (in frame deletion of codons 211-507) or mutated to Phe.

Comments

The addition of dosYY.sev.hs strongly suppresses the rough eye phenotype seen in cswCS.hs.2sev; dos1.46 flies. In dos1.46/dos2.42 flies rescued by dosYY.sev.hs, occasional ommatidia are observed that lack a R7 or R1-6 photoreceptor cell. Heat shock expression of dosYY.sev.hs rescues the lethality and almost rescues the eye phenotype seen in dos1.46/dos2.42 or homozygous dosP115 flies.
