What is the official name of the PML gene?
The official name of this gene is “promyelocytic leukemia.”
PML is the gene's official symbol. The PML gene is also known by other names, listed below.

What is the normal function of the PML gene?
The PML gene provides instructions for a protein that acts as a tumor suppressor, which means it prevents cells from growing and dividing too rapidly or in an uncontrolled way. The PML protein is found in distinct structures in the nucleus of a cell called PML nuclear bodies (PML-NBs). In the PML-NBs, the PML protein interacts with other proteins that are involved in cell growth and division (proliferation) and self-destruction (apoptosis). The PML protein is able to block cell proliferation and induce apoptosis in combination with other proteins. Researchers believe that the structure of the PML-NBs is required for blocking proliferation and inducing apoptosis.
Does the PML gene share characteristics with other genes?
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.
