What is the official name of the EYA1 gene?
The official name of this gene is “eyes absent homolog 1 (Drosophila).”
EYA1 is the gene's official symbol. The EYA1 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 EYA1 gene?
The EYA1 gene provides instructions for making a protein that plays a role in regulating the activity of other genes. Based on this role, the EYA1 protein is called a transcription factor or transcription coactivator.
The EYA1 protein interacts with several other proteins, including a group known as SIX proteins, to activate genes that are important for normal development. Before birth, these protein interactions appear to be essential for the normal formation of many tissues, including the second branchial arch (a structure that gives rise to tissues in the front and side of the neck) and the eyes, ears, and kidneys.
Does the EYA1 gene share characteristics with other genes?
The EYA1 gene belongs to a family of genes called PTP (protein tyrosine phosphatases).
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.
