Heme Oxygenase-1 (HO-1) also known as Hsp32, is the inducible isoform of heme oxygenase that catalyzes the NADPH, oxygen, and cytochrome P450 reductase dependent oxidation of heme to carbon monoxide, ferrous iron and biliverdin which is rapidly reduced to bilirubin. These products of the HO reaction have important physiological effects: carbon monoxide is a potent vasodilator and has been implicated to be a physiological regulator of cGMP and vascular tone; biliverdin and its product bilirubin are potent antioxidants; "free" iron increases oxidative stress and regulates the expression of many mRNAs (e.g., DCT-1, ferritin and transferring receptor) by affecting the conformation of iron regulatory protein (IRP)-1 and its binding to iron regulatory elements (IREs) in the 5'- or 3'- UTRs of the mRNAs. To date, three identified heme oxygenase isoforms are part of the HO system that catalyze heme into biliverdin and carbon monoxide. These are inducible HO-1 or Hsp32, constitutive HO-2 that is abundant in the brain and testis, and HO-3 which is related to HO-2 but is the product of a different gene. The HO system is the rate-limiting step in heme degradation and HO activity decreases the levels of heme which is a well known potent catalyst of lipid peroxidation and oxygen radical formation.

血紅素加氧酶-1 （HO-1） 也稱為 Hsp32，是血紅素加氧酶的誘導(dǎo)亞型，可催化血紅素的 NADPH、氧氣和細胞色素 P450 還原酶依賴性氧化為一氧化碳、亞鐵和膽綠素，并迅速還原為膽紅素。HO反應(yīng)的這些產(chǎn)物具有重要的生理作用：一氧化碳是一種有效的血管擴張劑，并且被認為是cGMP和血管張力的生理調(diào)節(jié)劑;膽綠素及其產(chǎn)物膽紅素是有效的抗氧化劑;“游離"鐵通過影響鐵調(diào)節(jié)蛋白（IRP）-1的構(gòu)象及其與mRNA的1'或5'-UTR中的鐵調(diào)節(jié)元件（IRE）的結(jié)合，增加氧化應(yīng)激并調(diào)節(jié)許多mRNA（例如DCT-3，鐵蛋白和轉(zhuǎn)移受體）的表達。
