What is the official name of the ATP2C1 gene?
The official name of this gene is “ATPase, Ca++ transporting, type 2C, member 1.”
ATP2C1 is the gene's official symbol. The ATP2C1 gene is also known by other names, listed below.

What is the normal function of the ATP2C1 gene?
The ATP2C1 gene provides instructions for making a protein called hSPCA1. This protein is an adenosine triphosphate (ATP)-powered calcium pump, which uses energy from ATP molecules to pump charged calcium atoms (calcium ions) across cell membranes. Specifically, the hSPCA1 protein transports calcium ions into a cell structure called the Golgi apparatus, where they are stored until needed. The appropriate storage and release of calcium is essential for many cell activities, including cell growth and division, cell movement, and attachment of cells to one another (cell adhesion).
The hSPCA1 protein also transports manganese ions into the Golgi apparatus. Manganese works with a variety of enzymes and is involved in processing newly formed proteins.
The hSPCA1 protein is present in cells throughout the body. It appears to be particularly important for the normal function of cells called keratinocytes, which are found in the outer layer of the skin (the epidermis).
Does the ATP2C1 gene share characteristics with other genes?
The ATP2C1 gene belongs to a family of genes called ATP (ATPases).
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.
