What is the official name of the SLC45A2 gene?
The official name of this gene is “solute carrier family 45 member 2.”
SLC45A2 is the gene's official symbol. The SLC45A2 gene is also known by other names, listed below.

What is the normal function of the SLC45A2 gene?
The SLC45A2 gene (also called MATP) provides instructions for making a protein that is located in specialized cells called melanocytes. These cells produce a pigment called melanin, which is the substance that gives skin, hair, and eyes their color. Melanin is also found in the light-sensitive tissue at the back of the eye (the retina), where it plays a role in normal vision.
Although the exact function of the SLC45A2 protein is unknown, it is likely involved in the production of melanin. This protein probably transports molecules necessary for the normal function of melanosomes, which are the structures in melanocytes where melanin is produced. Studies suggest that certain common variations (polymorphisms) in the SLC45A2 gene may be associated with normal differences in skin, hair, and eye coloring.
Does the SLC45A2 gene share characteristics with other genes?
The SLC45A2 gene belongs to a family of genes called SLC (solute carriers).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
