Organisms of all domains of life use photoreceptor proteins to sense and respond to light. The light-sensitivity of photoreceptor… Expand Vision is the most fundamental of our senses initiated when photons are absorbed by the rod and cone photoreceptor neurons of the… Expand Light induces massive translocation of major signaling proteins between the subcellular compartments of photoreceptors. Among… Expand Retinal bipolar cells are interneurons that transmit visual signals from photoreceptors to ganglion cells. Although the visual… Expand G protein-coupled receptors (GPCRs) are involved in the control of every aspect of our behavior and physiology. This is the… Expand SUMMARY
Capacitative calcium entry (CCE) describes CA2+ influx into cells that replenishes CA2+ stores emptied through the action… Expand A current paradigm for visual function centers on the metarhodopsin I (MI) to metarhodopsin II (MII) conformational transition as… Expand The effect of phospholipid bilayer acyl chain packing free volume on the equilibrium concentration of the form of photolyzed… Expand Rod transducin (Tr), a heterotrimeric GTP-binding protein composed of alpha, beta, and gamma subunits, couples photolysis of… Expand Retinal transducin was previously shown to be farnesylated on its gamma subunit. This farnesylation reaction on a cysteine… Expand
