Examples

• Iodopsins are responsible for detecting different wavelengths of light in the human eye.
• The three types of iodopsins in cone cells respond to red, green, and blue light.
• Color blindness can result from defects in iodopsin production or function.
• Researchers study iodopsins to understand how the eye perceives color.
• Unlike rhodopsin in rod cells, iodopsins function optimally in bright lighting.
