The cloned cDNA for rat thromboxane (TX) synthase with a size of 1851 bp contained a
1599‐bp open reading frame which encoded a 533‐amino acid protein sharing 79.7%
identity with human TX synthase. RNA blot analysis was carried out with rat cells and
tissues. Rat peritoneal macrophages most abundantly expressed mRNA for TX synthase,
and its level was not changed by in vivo stimulation of casein. Bone marrow, spleen, lung
and thymus also expressed the TX synthase gene. These findings suggest the possibility …
The cloned cDNA for rat thromboxane (TX) synthase with a size of 1851 bp contained a 1599‐bp open reading frame which encoded a 533‐amino acid protein sharing 79.7% identity with human TX synthase. RNA blot analysis was carried out with rat cells and tissues. Rat peritoneal macrophages most abundantly expressed mRNA for TX synthase, and its level was not changed by in vivo stimulation of casein. Bone marrow, spleen, lung and thymus also expressed the TX synthase gene. These findings suggest the possibility that TXA2 plays a role in the immune system.
