What is the official name of the THAP1 gene?
The official name of this gene is “THAP domain containing, apoptosis associated protein 1.”
THAP1 is the gene's official symbol. The THAP1 gene is also known by other names, listed below.

What is the normal function of the THAP1 gene?
The THAP1 gene provides instructions for making a protein that is a transcription factor, which means that it attaches (binds) to specific regions of DNA and regulates the activity of other genes. Through this function, it is thought to help control several processes in the body, including the growth and division (proliferation) of endothelial cells, which line the inside surface of blood vessels and other circulatory system structures called lymphatic vessels. The THAP1 protein also plays a role in the self-destruction of cells that are no longer needed (apoptosis).
Does the THAP1 gene share characteristics with other genes?
The THAP1 gene belongs to a family of genes called THAP domain containing (THAP (C2CH-type zinc finger) 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.
