Summary: Enables thromboxane receptor activity. Involved in several processes, including cellular response to lipopolysaccharide; positive regulation of vasoconstriction; and response to testosterone. Located in acrosomal vesicle. Used to study adult respiratory distress syndrome; kidney failure; thrombocytopenia; and toxic shock syndrome. Human ortholog(s) of this gene implicated in aspirin-induced respiratory disease; asthma; and blood platelet disease. Orthologous to human TBXA2R (thromboxane A2 receptor).

the long-lasting oligemia following cortical spreading depression consists of at least two distinct temporal phases, mediated by preferential actions of COX-1- and COX-2-derived prostanoids: an initial phase mediated by COX-1 that involves TXA2 followed by a later phase, mediated by COX-2 and PGF2alpha.

Data suggest that thromboxane A2/Tbxa2r-mediated vasoconstriction of intracavernous small penile arteries depends on Ca2+ influx through L-type calcium channels and TRP (transient receptor potential) channels, and ROCK- (Rho kinase)-dependent mechanisms in vascular smooth muscle.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
