Researchers found that a light-sensing receptor called rhodopsin plays a critical role in sensing temperature, particularly in the comfortable range. The discovery suggests that rhodopsin may have been used originally for temperature detection before its function as a light receptor.
A team of researchers has discovered that arrestin molecules bind to two rhodopsin molecules in bright light, but one in low light, challenging the long-held assumption of a single binding interaction. This finding has implications for understanding other senses and physiological functions controlled by G-protein coupled receptors.
Researchers have uncovered the efficient survival mechanisms of Oxyrrhis marina, a microscopic dinoflagellate that can harness energy from light and digest prey with acquired genes. The study shows that this unique organism has picked up a gene for photosynthesis from its bacterial prey.
Researchers have discovered how rhodopsin communicates with transducin in the retina, shedding light on vision's molecular processes. This breakthrough could lead to more targeted treatments for diseases like diabetes, allergies, and certain cancers.
Researchers at NYU's Center for Developmental Genetics identified a new class of photoreceptors in the retina of fruit flies that co-express two ultraviolet-sensitive rhodopsins. This discovery may have implications for understanding the regulation of color vision and olfactory receptors.
A recent study found that antibodies targeting the Chagas parasite also block rhodopsin, a molecule essential for converting light into electrical impulses. This discovery sheds light on the molecular mechanisms underlying the disease's vision problems. Researchers hope to develop new drugs or vaccines to combat the parasite and improv...
Researchers find that moderate light exposure causes complete retinal degeneration within a month, but lower levels cause slower and reversible damage. This study provides new insights into the interaction of genetics and environment in causing eye disease and suggests potential treatments for preventing blindness.
Researchers found that engineered fruit flies with resistant rhodopsin protein retained vision twice as long as normal flies, but eventually developed blindness due to delayed decay of rhodopsin. The study suggests that degradation of visual proteins contributes to vision loss and may help reduce blindness severity in rare individuals.
Researchers discovered that constant light causes visual impairment through a separate mechanism from retinal degeneration. A decline in rhodopsin concentration leads to blindness, and inhibiting its degradation may reduce the severity of visual impairment.
Researchers found a novel rhodopsin protein in bacteria that can distinguish between blue and orange light, enabling more efficient harvesting of light for photosynthesis. This discovery sheds light on the role of cell membranes in biological functions and has potential applications in nano-machinery as a color-sensor.
Researchers have discovered a crucial link between zinc and retinitis pigmentosa, a degenerative eye disease that leads to blindness. The study suggests that trace metals like zinc play a critical role in protein function, with implications for treating other neurodegenerative diseases.
Researchers have identified a molecular understanding of the abnormal proteins causing retinitis pigmentosa, a degenerative eye disease. They will now focus on designing effective drugs to delay disease progression by stabilizing the mutated rhodopsin protein.
Vision researchers found that rhodopsin molecules pair up in neat double rows on the outer-segment disc membranes of rods. This arrangement allows for efficient absorption of dim light and amplification of faint signals, enabling the brain to detect individual photons.
Researchers recreated a 240-million-year-old protein to study the vision of dinosaur ancestors, finding evidence that they may have had dim-light vision. The discovery offers insights into how biologically important molecules evolved over time and paves the way for further studies on ancient species.
Researchers have discovered a genetic mutation in English mastiffs that causes retinal dysfunction and degeneration, mirroring human dominant retinitis pigmentosa. The study aims to find treatments and cures for inherited forms of blindness in humans by testing therapies first in dogs.
