U5 snRNP

U5 snRNP (small nuclear ribonucleoprotein) is a key component of the spliceosome, a complex molecular machine in cells that removes non-coding regions (introns) from messenger RNA (mRNA). U5 snRNP helps ensure that the remaining coding regions (exons) are accurately joined together during mRNA processing. It works by aligning and stabilizing the RNA segments to facilitate precise splicing, which is crucial for producing correct and functional proteins. U5 snRNP interacts with other spliceosome components, playing a central role in the accurate editing of genetic messages before they leave the cell for protein production.
