What is the official name of the MCOLN1 gene?
The official name of this gene is “mucolipin 1.”
MCOLN1 is the gene's official symbol. The MCOLN1 gene is also known by other names, listed below.

What is the normal function of the MCOLN1 gene?
The MCOLN1 gene provides instructions for making a protein called mucolipin-1. This protein is located in the membranes of lysosomes and endosomes, compartments within the cell that digest and recycle materials. While its function is not completely understood, mucolipin-1 plays a role in the transport (trafficking) of fats (lipids) and proteins between lysosomes and endosomes.
Mucolipin-1 acts as a channel, allowing positively charged atoms (cations) to cross the membranes of lysosomes and endosomes. It remains unclear which cations are allowed to flow through this channel. Mucolipin-1 appears to be important for the development and maintenance of the brain and light-sensitive tissue at the back of the eye (retina). In addition, this protein is likely critical for normal functioning of the cells in the stomach that produce digestive acids.
Does the MCOLN1 gene share characteristics with other genes?
The MCOLN1 gene belongs to a family of genes called TRP (transient receptor potential cation channels).
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.
