A ribostome is a hypothetical cellular structure proposed to be involved in the assembly of ribosomes, which are essential for protein synthesis in cells. It is thought to facilitate the organization and modification of ribosomal RNA and proteins during ribosome biogenesis. The concept of ribostomes aims to enhance our understanding of the intricate processes governing ribosome formation and function. However, it is important to note that ribostomes have not been definitively identified or characterized in biological research.
