CHROMOSOMAL LOCALIZATION OF 3 MOUSE DIACYLGLYCEROL KINASE (DAGK) GENES - GENES SHAVING SEQUENCE HOMOLOGY TO THE DROSOPHILA-RETINAL-DEGENERATION-A (RDGA) GENE

There is growing evidence to support some form of light-activated phosphoinositide signal transduction pathway in the mammalian retina. Although this pathway plays no obvious role in mammalian phototransduction, mutations in this pathway cause retinal degenerations in Drosophila. These include the retinal degeneration A mutant, which is caused by an alteration in an eye-specific diacylglycerol kinase (DAGK) gene. In our efforts to consider genes mutated in Drosophila as candidates for mammalian eye disease, we have initially determined the map position of three DAGK genes in the mouse.
