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

What is the normal function of the THPO gene?
The THPO gene provides instructions for making a protein called thrombopoietin that promotes the growth and division (proliferation) of cells. This protein attaches to (binds) and turns on (activates) the thrombopoietin receptor, which stimulates several signaling pathways that transmit chemical signals from outside the cell to the cell's nucleus. These pathways are important for controlling the production of blood cells.
Thrombopoietin is especially important for the proliferation of certain blood cells called megakaryocytes, which produce platelets, the cells involved in blood clotting. Research suggests that thrombopoietin signaling may also play a role in the renewal of hematopoietic stem cells, which are stem cells located within the bone marrow that have the potential to develop into red blood cells, white blood cells, and platelets.
Does the THPO gene share characteristics with other genes?
The THPO gene belongs to a family of genes called endogenous ligands (endogenous ligands).
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.
