RNA recognition motifs (RRMs)

RNA recognition motifs (RRMs) are common protein domains that enable proteins to specifically bind to RNA molecules. They are typically about 80–90 amino acids long and contain a conserved structure that interacts with RNA's nucleotide sequences. RRMs play essential roles in various cellular processes, such as gene expression regulation, RNA processing, and transport, by helping proteins recognize and bind target RNA molecules accurately. Their ability to form multiple contacts with RNA makes them versatile and vital for maintaining proper RNA function within the cell.
