Summary

TBXA2R (thromboxane A2 receptor, HGNC:11608) is a protein-coding gene on chromosome 19p13.3, encoding Thromboxane A2 receptor (P21731). Receptor for thromboxane A2 (TXA2), a potent stimulator of platelet aggregation.

This gene encodes a member of the G protein-coupled receptor family. The protein interacts with thromboxane A2 to induce platelet aggregation and regulate hemostasis. A mutation in this gene results in a bleeding disorder. Multiple transcript variants encoding different isoforms have been found for this gene.

All UniProt accessions (2): P21731, K7ER80

UniProt curated annotations — full annotation on UniProt →

Function. Receptor for thromboxane A2 (TXA2), a potent stimulator of platelet aggregation. The activity of this receptor is mediated by a G-protein that activates a phosphatidylinositol-calcium second messenger system. In the kidney, the binding of TXA2 to glomerular TP receptors causes intense vasoconstriction. Activates phospholipase C. Activates adenylyl cyclase. Inhibits adenylyl cyclase.

Subunit / interactions. Interacts with RPGRIP1L. Interacts with PSMA3. Interacts with RACK1; the interaction regulates TBXA2R cell surface expression.

Subcellular location. Cell membrane.

Disease relevance. Bleeding disorder, platelet-type, 13 (BDPLT13) [MIM:614009] A disorder characterized by reduced platelet aggregation and a tendency to mild mucocutaneous bleeding. Disease susceptibility is associated with variants affecting the gene represented in this entry.

Similarity. Belongs to the G-protein coupled receptor 1 family.
