Source	Thromboxane A2 is produced in platelets, polymorphonuclear leukocytes, macrophages, lung, kidney and spleen of various animals upon various biological stimulations Moncada_S et al..
Chemical Synthesis
Metabolism	Prostaglandin H2 produced by the catalysis of cyclooxygenase is further metabolized to thrombaxne A2 by thromboxane synthaase. Thromboxane A2 is unstable (half life 30 sec) and its oxetane ring is hydrolyzed to hemiacetal thromboxane B2 Needleman_P et al.. The major urinary metabolite of tromboxane B2 is 2,3-dinor-thromboxane B2 Kindahl_H , and 11-dehydro-thromboxane B2 is known as a suitble parameter for monitoring thromboxane production in human Westlund_P et al..
Biological Activity	Thromboxane A2 aggregates platelets and constricts blood vessels and bronchi Whittle_BJ et al.. Thromboxane A2 binds to a specific recptor (TP) coupled to Gq protein Ushikubi_F et al..
Genetic Information	cDNA and genomic DNA for thromboxane A synthase Tanabe_T et al. and those fro thromboxane A2 receptor Ushikubi_F et al. were cloned.
Note	Stability:unstable in water around neutrality with a half life of about 40 sec at 37°C and decomposes to TXB2 and 12-hydroxy-5,8,10-heptadecatrienoic acid Moncada_S et al..
