What is the official name of the GRM6 gene?
The official name of this gene is “glutamate receptor, metabotropic 6.”
GRM6 is the gene's official symbol. The GRM6 gene is also known by other names, listed below.

What is the normal function of the GRM6 gene?
The GRM6 gene provides instructions for making a protein called metabotropic glutamate receptor 6 (mGluR6). This protein is a glutamate receptor, which is a type of protein that attaches (binds) to the signaling molecule glutamate on the surface of cells. The mGluR6 protein is found within the membrane that surrounds cells called bipolar cells, which are part of the light-sensitive tissue at the back of the eye (retina). Bipolar cells receive visual signals from cells called rods that are used to see in low light. Rod cells release glutamate, which then binds to mGluR6 on bipolar cells. This binding ultimately triggers bipolar cells to transmit the visual signals to other retinal cells and eventually to the brain.
Does the GRM6 gene share characteristics with other genes?
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.
