What is the official name of the ATL1 gene?
The official name of this gene is “atlastin GTPase 1.”
ATL1 is the gene's official symbol. The ATL1 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 ATL1 gene?
The ATL1 gene provides instructions for producing a protein called atlastin-1. Atlastin-1 is found throughout the body, particularly in the brain. In cells, this protein is found in structures known as the endoplasmic reticulum and the Golgi apparatus, which are involved in the movement of proteins and cell components within the cell. Atlastin-1 likely plays a role in the transportation of cell components and in the formation of the endoplasmic reticulum and Golgi apparatus, each of which is involved in the growth of axons (specialized extensions of nerve cells that transmit nerve impulses). Atlastin-1 is necessary for the formation and growth of axons; however, its precise function remains unclear.
