Nox4 cDNA Clones

NOX4 (RENOX) is a renal gp91-phox homolog which functions in the kidney as an oxygen sensor and regulates the synthesis of erythropoietin. This protein is highly expressed at the site of erythropoietin production in the proximal convoluted tubule epithelial cells of the renal cortex.

NOX-4 is also expressed in fetal tissues, placenta, glioblastoma and vascular cells. Like gp91-phox, the enzymatic activity of NOX4 produces superoxide anions. In vascular cells, the addition of angiotensin II ...
