WebA ribosome is an organelle that serves as the site of protein synthesis. It is composed of two ribosomal RNA subunits that wrap around mRNA to start the process of translation, followed by protein synthesis. Smooth ER (SER) lacks these ribosomes. One of the main functions of the smooth ER is in the synthesis of lipids. 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.
