These studies are the first to determine the structure and organization of the 5' end of the thromboxane receptor gene and demonstrate that thromboxane receptor gene expression can be regulated by activation of protein kinase C via induction of an AP-2 -like nuclear factor binding to upstream promoter elements .
 DNA: upstream promoter elements; protein: AP-2 -like nuclear factor; protein: thromboxane receptor; DNA: thromboxane receptor gene; DNA: thromboxane receptor gene; protein: thromboxane receptor; protein: AP-2; protein: protein kinase C
