Fibrillarin is a protein that plays a crucial role in the biogenesis of ribosomes, which are essential cellular structures responsible for protein synthesis. It is primarily located in the nucleolus, a subnuclear structure where ribosomal RNA (rRNA) is synthesized and processed, and where ribosome assembly occurs.
