WebThis is one facet of ribosome stress, which we describe as a two-way process. Ribosomes are regulated by stress signaling, such as energy status, but also sense stress and enact appropriate responses. Stress sensing starts at ribosomes synthesis, which is linked to cell fate by ribosome components and biogenesis factors.
