RNase L is one of the key enzymes involved in the molecular mechanisms of interferon (IFN) function. Upon binding with its activator, 5'-phosphorylated and 2'-5' linked oligoadenylates (2-5A), RNase L plays an important role in the antiviral and anti-proliferative functions of IFN, and exerts proapoptotic activity independent of IFN. These biological activities are thought to occur through the RNase L-dependent regulation of RNA stability and expression; however, the molecular targets of RNase L remain largely unknown. Recently we have found that RNase L regulates the expression of several proinflammatory genes. Our research has focused on investigating the molecular mechanism by which RNase L regulates the expression of these proinflammatory genes and the role of RNase L in inflammatory diseases.
