Many cellular stresses have been shown to stimulate JNK activation. In this review, we focus on ribotoxic stresses based on their multiple biological potencies including anti-HIV-1 activity. Some of the functions of ribotoxins and the signaling transduction pathway that mediated are mentioned. Different from other stimulators, ribotoxic stresses act on special motifs of 28S rRNA in translationally active mammal ribosomes. Binding and damaging on the motif leads to JNK activation and subsequently biological response to the signal initiator, which is named ribotoxic stress response.
