RNA binding proteins (RBPs) play a crucial role in the formation and function of membrane-less organelles (MLOs) in cells. MLOs, also known as RNA granules or bodies, are dynamic structures composed of RNA and proteins that regulate various cellular processes. MLOs are like tiny factories that control how the cell works.

RBPs perform several tasks:

1. They bring specific RNA molecules to the MLOs.
2. They help keep RNA molecules stable or break them down.
3. They interact with other proteins to build the MLO structure.
4. They help create a special environment that allows MLOs to form.
5. They direct RNA molecules to the right location within the cell.
6. They regulate how RNA molecules are processed and used.
7. They organize the internal structure of MLOs.
8. They control when MLOs form, dissolve, or merge.

By doing these tasks, RBPs play a crucial role in managing cellular processes like stress response, RNA processing, and gene expression. Think of RBPs as managers that help keep the cell’s factories running smoothly.
