Melanopsin Ganglion Cells Use a Membrane-Associated Rhabdomeric Phototransduction Cascade
Journal of Neurophysiology, 2008 Intrinsically photosensitive retinal ganglion cells (ipRGCs) are photoreceptors of the mammalian eye that drive pupillary responses, synchronization of circadian rhythms, and other reflexive responses to daylight. Melanopsin is the ipRGC photopigment, but the signaling cascade through which this invertebrate-like opsin triggers the photocurrent in ...

Neural superposition and oscillations in the eye of the blowfly [PDF]
, 1987 Neural superposition in the eye of the blowfly Calliphora erythrocephala was investigated by stimulating single photoreceptors using corneal neutralization through water immersion.

Two light-dependent conductances in Lima rhabdomeric photoreceptors. [PDF]
The Journal of general physiology, 1991 Light-dependent membrane currents were recorded from solitary Lima photoreceptors with the whole-cell clamp technique. Light stimulation from a holding voltage near the cell's resting potential evokes a transient inward current graded with light intensity, accompanied by an increase in membrane conductance.

PLoS Genetics, 2016 Polarized membrane trafficking is essential for the construction and maintenance of multiple plasma membrane domains of cells. Highly polarized Drosophila photoreceptors are an excellent model for studying polarized transport.

Fly eyes are not still: a motion illusion in Drosophila flight supports parallel visual processing. [PDF]
, 2020 Most animals shift gaze by a 'fixate and saccade' strategy, where the fixation phase stabilizes background motion. A logical prerequisite for robust detection and tracking of moving foreground objects, therefore, is to suppress the perception of ...

The Drosophila photoreceptor as a model system for studying signalling at membrane contact sites [PDF]
, 2016 Several recent studies have demonstrated the existence of membrane contact sites (MCS) between intracellular organelles in eukaryotic cells. Recent exciting studies have also demonstrated the existence of biomolecular interactions at these contact sites ...

Mechanism of arrestin 2 function in rhabdomeric photoreceptors.
Journal of Biological Chemistry, 1994 Arrestins have emerged as one family of proteins that mediate the inactivation of G-protein-coupled receptors. We have isolated cDNA clones encoding two arrestin isoforms of the dipteran visual system, Calliphora arrestin 1 (Arr1) and arrestin 2 (Arr2).

Rhabdomere biogenesis in Drosophila photoreceptors is acutely sensitive to phosphatidic acid levels [PDF]
Journal of Cell Biology, 2009 Phosphatidic acid (PA) is postulated to have both structural and signaling functions during membrane dynamics in animal cells. In this study, we show that before a critical time period during rhabdomere biogenesis in Drosophila melanogaster photoreceptors, elevated levels of PA disrupt membrane transport to the apical domain.

Linking eye design with host symbiont relationships in pontoniine shrimps (crustacea, decapoda, palaemonidae) [PDF]
, 2014 Symbiosis is prevalent in the marine environment with many studies examining the effects of such interactions between host and symbiont. Pontoniine shrimps are a group whose ecology is characterised by symbiotic interactions.
