RNase L: Proteins and Enzymes

RNase L is a virally induced endoribonuclease that is also the terminal factor of the anti-viral action of interferon. Activation of RNase L results in inhibition of viral proliferation through total RNA degradation. Activation of RNase L has also been determined to degrade RNA, thus, initiating a cellular stress response, inducing apoptosis. Since mutations in RNase L relate to an increased incidence of prostate cancer, the activation of RNase L is thought to function in counteracting prostate cancer, via apoptosis.
