What is the official name of the ANK1 gene?
The official name of this gene is “ankyrin 1, erythrocytic.”
ANK1 is the gene's official symbol. The ANK1 gene is also known by other names, listed below.

What is the normal function of the ANK1 gene?
The ANK1 gene provides instruction for making a protein called ankyrin-1. This protein is primarily active (expressed) in red blood cells, but it is also found in muscle and brain cells. In red blood cells, ankyrin-1 is located at the cell membrane, where it attaches (binds) to other membrane proteins. The binding of membrane proteins to one another maintains the stability and structure of red blood cells but also allows for their flexibility. The proteins allow the cell to change shape without breaking when passing through narrow blood vessels.
In muscle and brain cells, ankyrin-1 performs similar functions, binding to other membrane proteins to play a role in cell stability, cell movement, and other cell functions.
Does the ANK1 gene share characteristics with other genes?
The ANK1 gene belongs to a family of genes called ANKRD (ankyrin repeat domain containing).
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.
