The protein O-glucosyltransferase Rumi modifies eyes shut to promote rhabdomere separation in Drosophila. [PDF]
PLoS Genetics, 2014 The protein O-glucosyltransferase Rumi/POGLUT1 regulates Drosophila Notch signaling by adding O-glucose residues to the Notch extracellular domain. Rumi has other predicted targets including Crumbs (Crb) and Eyes shut (Eys), both of which are involved in

Drosophila photoreceptor tethering by a laminin-Eys scaffold [PDF]
iScienceSummary: Visual acuity in Drosophila requires precise photoreceptor alignment along the optical axis, maintained by longitudinal tension between a rigid cornea and a contractile retinal base. Here, we identify the rhabdomere caps—an extracellular matrix (

Comprehensive study of SNAREs involved in the post-Golgi transport in Drosophila photoreceptors [PDF]
Frontiers in Cell and Developmental BiologyPolarized transport is essential for the construction of multiple plasma membrane domains within cells. Drosophila photoreceptors serve as excellent model systems for studying the mechanisms of polarized transport.

Optimizing the use of a sensor resource for opponent polarization coding [PDF]
PeerJ, 2017 Flies use specialized photoreceptors R7 and R8 in the dorsal rim area (DRA) to detect skylight polarization. R7 and R8 form a tiered waveguide (central rhabdomere pair, CRP) with R7 on top, filtering light delivered to R8.

tsCRISPR based identification of Rab proteins required for the recycling of Drosophila TRPL ion channel [PDF]
Frontiers in Cell and Developmental BiologyIn polarized cells, the precise regulation of protein transport to and from the plasma membrane is crucial to maintain cellular function. Dysregulation of intracellular protein transport in neurons can lead to neurodegenerative diseases such as Retinitis

Functional characterization of four opsins and two G alpha subtypes co-expressed in the molluscan rhabdomeric photoreceptor [PDF]
BMC Biology, 2023 Background Rhabdomeric photoreceptors of eyes in the terrestrial slug Limax are the typical invertebrate-type but unique in that three visual opsins (Gq-coupled rhodopsin, xenopsin, Opn5A) and one retinochrome, all belonging to different groups, are co ...

In vivo identification of Drosophila rhodopsin interaction partners by biotin proximity labeling [PDF]
Scientific ReportsProteins exert their function through protein–protein interactions. In Drosophila, G protein-coupled receptors like rhodopsin (Rh1) interact with a G protein to activate visual signal transduction and with arrestins to terminate activation.

Angular sensitivity of blowfly photoreceptors: intracellular measurements and wave-optical predictions [PDF]
, 1984 The angular sensitivity of blowfly photoreceptors was measured in detail at wavelengths λ = 355, 494 and 588 nm. The measured curves often showed numerous sidebands, indicating the importance of diffraction by the facet lens.

Mechanisms underlying stage-1 TRPL channel translocation in Drosophila photoreceptors. [PDF]
PLoS ONE, 2012 BACKGROUND:TRP channels function as key mediators of sensory transduction and other cellular signaling pathways. In Drosophila, TRP and TRPL are the light-activated channels in photoreceptors.
