Rabbit anti-Human Thromboxane synthase Polyclonal Antibody

Uniprot Id

P24557

Target Species

Human

Target Name

TBXAS1

Target Full Name

Thromboxane-A synthase

Target Function

Catalyzes the conversion of prostaglandin H2 (PGH2) to thromboxane A2 (TXA2), a potent inducer of blood vessel constriction and platelet aggregation. Cleaves also PGH2 to 12-hydroxy-heptadecatrienoicacid (12-HHT) and malondialdehyde, which is known to act as a mediator of DNA damage. 12-HHT and malondialdehyde are formed stoichiometrically in the same amounts as TXA2. Additionally, displays dehydratase activity, toward (15S)-hydroperoxy-(5Z,8Z,11Z,13E)-eicosatetraenoate (15(S)-HPETE) producing 15-KETE and 15-HETE.

Target Involvement

Ghosal hematodiaphyseal dysplasia (GHDD)

Target Subcellular Location

Endoplasmic reticulum membrane; Multi-pass membrane protein.

Target Protein Families

Cytochrome P450 family

Target Tissue Specificity

Platelets, lung, kidney, spleen, macrophages and lung fibroblasts.

Target Synonyms

TBXAS1; CYP5; CYP5A1; TXAS; Thromboxane-A synthase; TXA synthase; TXS; Cytochrome P450 5A1; Hydroperoxy icosatetraenoate dehydratase

Target Background

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.
