What is the official name of the YWHAE gene?
The official name of this gene is “tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein, epsilon polypeptide.”
YWHAE is the gene's official symbol. The YWHAE gene is also known by other names, listed below.

What is the normal function of the YWHAE gene?
The YWHAE gene provides instructions for making the 14-3-3 epsilon (ε) protein, which is part of the large 14-3-3 protein family. Proteins in this family attach (bind) to other proteins involved in cell signaling. 14-3-3 proteins either turn on (activate) or turn off (inactivate) these other proteins. The 14-3-3ε protein helps to regulate a variety of processes including cell division and sensitivity to insulin, a hormone that helps control blood sugar levels.
The 14-3-3ε protein is active in tissues throughout the body, although its function is sometimes unclear. In the brain, this protein is involved in directing the movement of nerve cells (neuronal migration) by binding to other proteins involved in this process. It is thought that the 14-3-3ε protein is critical for proper neuronal migration and normal brain development.
