Cryptochrome and rhodopsin pigments

Cryptochrome and rhodopsin pigments. Rhodopsin is a pigment found in the rod photoreceptor cells in the retina of the human eye, where it absorbs light falling on the retina. Here, four rhodopsin molecules are shown embedded in the membrane (across top and bottom) of cells in the eyes retina. The membrane is shown as a lipid bilayer. Inside the cell is a molecule of a cryptochrome (centre), anchored to the membrane (pink strands). Cryptochromes are capable of mediating a response to light falling on the retina, triggering a cascade of other reactions (the CRY pathway). They are also involved in the circadian rhythm

EDITORS COMMENTS
This print showcases the intricate world of cryptochrome and rhodopsin pigments found in the human eye. Rhodopsin, a pigment located in the rod photoreceptor cells of the retina, plays a crucial role in absorbing light that falls on the retina. The image beautifully captures four rhodopsin molecules embedded within the membrane of these retinal cells, depicted as a lipid bilayer. At the center of attention is a molecule of cryptochrome, anchored to the pink strands of the membrane. Cryptochromes possess remarkable abilities to respond to light falling on the retina, triggering a cascade of reactions known as the CRY pathway. Additionally, they are intricately involved in regulating our circadian rhythm. The white background adds an artistic touch to this scientific illustration, emphasizing its importance within biology and physiology. This artwork delves into various fields such as biochemistry and molecular biology while highlighting key aspects like proteins, pigments, biomolecules, and membranes. Claus Lunau's masterful portrayal not only provides insight into ophthalmology but also offers a deeper understanding of how our eyes function at a molecular level. It serves as a reminder that even within our bodies' most complex systems lie extraordinary wonders waiting to be explored.
