What is the official name of the FOXL2 gene?
The official name of this gene is “forkhead box L2.”
FOXL2 is the gene's official symbol. The FOXL2 gene is also known by other names, listed below.
Read more about gene names and symbols on the About page.
What is the normal function of the FOXL2 gene?
The FOXL2 gene provides instructions for making a protein that attaches (binds) to specific regions of DNA and helps control the activity of particular genes. On the basis of this role, the FOXL2 protein is called a transcription factor. The FOXL2 protein is active in the developing eyelids and ovaries before birth. This protein also plays a role in the maintenance of the ovaries throughout adult life. The specific function of the FOXL2 protein is unknown, but it is thought to be involved in many regulatory functions within cells.
The FOXL2 protein contains one area where a protein building block (amino acid) called alanine is repeated multiple times. This stretch of alanines is known as a polyalanine tract or poly(A) tract.
Does the FOXL2 gene share characteristics with other genes?
The FOXL2 gene belongs to a family of genes called FOX (forkhead box 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.
