What is the official name of the TAF1 gene?
The official name of this gene is “TATA-box binding protein associated factor 1.”
TAF1 is the gene's official symbol. The TAF1 gene is also known by other names, listed below.

What is the normal function of the TAF1 gene?
The TAF1 gene provides instructions for making part of a protein called transcription factor IID (TFIID). This protein is active in cells and tissues throughout the body, where it attaches (binds) to DNA. Transcription factor IID plays an essential role in regulating the activity of most genes.
The TAF1 gene is part of a complex region of DNA known as the TAF1/DYT3 multiple transcript system. This region consists of short stretches of DNA from the TAF1 gene plus some extra segments of genetic material near the gene. These stretches of DNA can be combined in different ways to create various sets of instructions for making proteins. Researchers believe that some of these variations are critical for the normal function of nerve cells (neurons) in the brain.
Does the TAF1 gene share characteristics with other genes?
The TAF1 gene belongs to a family of genes called chromatin-modifying enzymes (chromatin-modifying enzymes).
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.
