RRM (RNA Recognition Motif)

The RNA Recognition Motif (RRM) is a common structural domain found in proteins that bind to RNA molecules. It consists of a specific arrangement of amino acids forming a stable fold, allowing the protein to specifically recognize and attach to RNA sequences. This interaction is crucial for various cellular processes like gene regulation, RNA splicing, transport, and stability. Essentially, the RRM acts as a specialized tool within proteins to selectively identify and interact with RNA, enabling precise control over how genetic information is processed and used in cells.
