一般描述
HO2, or heme oxygenase 2, belongs to the heme oxygenase family that are essential enzyme in heme catabolism that cleave heme to form biliverdin which is subsequently converted to bilirubin by biliverdin reductase. HO2 is part of the calcium-sensitive potassium channel complex and enhances channel activity in normoxia. Knockdown of HO2 expression reduces channel activity, an effect that is reversed by carbon monoxide. Inhibition of calcium-sensitive potassium channels by hypoxia is dependent on HO2 expression and is augmented by HO2 stimulation.

Modulation of calcium-sensitive potassium (BK) channels by oxygen is important in several mammalian tissues, and in the carotid body it is crucial to respiratory control. However, the identity of the oxygen sensor remains unknown. We demonstrate that hemoxygenase-2 (HO-2) is

The physiological response of the carotid body is critically dependent upon oxygen-sensing by potassium channels expressed in glomus cells. One such channel is the large conductance, voltage- and calcium-dependent potassium channel, BK(Ca). Although it is well known that a decrease
