What is the normal function of the TAT gene?
The TAT gene provides instructions for making a liver enzyme called tyrosine aminotransferase. This enzyme helps break down the amino acid tyrosine, a protein building block found in many foods. Tyrosine aminotransferase is the first in a series of five enzymes that converts tyrosine to smaller molecules, which are excreted by the kidneys or used in reactions that produce energy.
How are changes in the TAT gene related to health conditions?
Where is the TAT gene located?
