The ELOVL4 gene provides instructions for making a protein that is found primarily in the retina, the specialized light-sensitive tissue that lines the back of the eye. Specifically, the ELOVL4 protein is produced in the retina's light-sensing cells (photoreceptors). The ELOVL4 protein is also found in the brain and skin, but less is known about its activity (expression) in these structures.
Normal function
The ELOVL4 gene provides instructions for making a protein that is found primarily in the retina, the specialized light-sensitive tissue that lines the back of the eye. Specifically, the ELOVL4 protein is produced in the retina's light-sensing cells (photoreceptors). The ELOVL4 protein is also found in the brain and skin, but less is known about its activity (expression) in these structures.
Inside photoreceptors, this protein is located in a cell structure called the endoplasmic reticulum that is involved in protein production, processing, and transport. The ELOVL4 protein plays a role in making a group of fats called very long-chain fatty acids. The protein helps add carbon molecules to long-chain fatty acids, making them very long-chain fatty acids. The function of the very long-chain fatty acids produced by the ELOVL4 protein is unknown.
