Summary This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. However, this protein is considered a member of the cytochrome P450 superfamily on the basis of sequence similarity rather than functional similarity. This endoplasmic reticulum membrane protein catalyzes the conversion of prostglandin H2 to thromboxane A2, a potent vasoconstrictor and inducer of platelet aggregation. The enzyme plays a role in several pathophysiological processes including hemostasis, cardiovascular disease, and stroke. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2008].

GeneRIFs: Gene References Into Functions What's a GeneRIF?

What is the normal function of the TBXAS1 gene?

The TBXAS1 gene provides instructions for making an enzyme called thromboxane A synthase 1. This enzyme acts as part of a chemical pathway called the arachidonic acid cascade. Through this multistep pathway, a molecule called arachidonic acid is processed to produce several molecules with diverse functions in the body. As part of this pathway, thromboxane A synthase 1 converts a molecule called prostaglandin H2 into another molecule called thromboxane A2. Thromboxane A2 is involved in normal blood clotting (hemostasis), playing critical roles in the narrowing of blood vessels (vasoconstriction) to slow blood flow and the clumping (aggregation) of blood cell fragments called platelets at the site of an injury.

Studies suggest that the activity of thromboxane A synthase 1 may also be important for bone remodeling, which is a normal process in which old bone is removed and new bone is created to replace it, and for the production of red blood cells in bone marrow.
