Journal ArticleDOI
Hereditary retinal degeneration in Drosophila melanogaster. A mutant defect associated with the phototransduction process.
TL;DR: It is proposed that the normal norpA gene codes for a product which, when activated, leads to the receptor potential, and which is inactivated by the product of the normal rdgB gene.
Journal ArticleDOI
Lipofuscin: resolution of discrepant fluorescence data
TL;DR: A reevaluation of the connection between blue-emitting lipid peroxidation products and the age-related lipofuscin granules of classical pathology is necessary.
Journal ArticleDOI
Two distantly positioned PDZ domains mediate multivalent INAD–phospholipase C interactions essential for G protein‐coupled signaling

TL;DR: It is reported that INAD directly binds to NORPA via two terminally positioned PDZ1 and PDZ5 domains, which allows for the multivalent INAD–NORPA interactions which are essential for G protein‐coupled phototransduction.
Journal ArticleDOI
Vitamin A deprivation and Drosophila photopigments
TL;DR: A study of the effects of vitamin A deprivation on the fine structure, photopigment content, and sensitivity of Drosophila photoreceptors supports the hypothesis that most of the intramembrane particles in invertebrate rhabdomeres are rhodopsin molecules.
Journal ArticleDOI
Sensitivity and photopigments of R1-6, a two-peaked photoreceptor, inDrosophila, Calliphora andMusca
TL;DR: These and previous results suggest that the two R1-6 spectral peaks are ultimately mediated by one rhodopsin, and calculations show electro-retinographic sensitivity to be extremely high, perhaps measurable at less than one absorbed quantum per rhabdomere.
