Other Information

**Key Characteristics:** Fibrillarin is a member of the fibrillarin family, which consists of three paralogous genes: FBL, FBLN1, and FBLN2. Fibrillarin is specifically associated with the nucleolus, where it plays a pivotal role in the biogenesis of ribosomal subunits. The gene is highly expressed in cells that require rapid proliferation and differentiation, such as erythroid progenitor cells, basal cells of prostate epithelium, and skeletal muscle satellite stem cells. **Pathways and Functions:** Fibrillarin is involved in several key pathways, including: 1. **RNA processing:** Fibrillarin is responsible for the 2'-O-methylation of snRNAs and rRNAs, which is essential for their proper processing and maturation. 2. **Ribosome biogenesis:** Fibrillarin contributes to the formation of ribosomal subunits by modifying rRNAs and facilitating their assembly. 3. **Cajal body formation:** Fibrillarin is a component of Cajal bodies, which are nuclear structures involved in the regulation of RNA processing and ribosome biogenesis. 4. **Chromatin remodeling:** Fibrillarin interacts with chromatin remodeling complexes to regulate gene expression and maintain genome stability. **Clinical Significance:** Fibrillarin has been implicated in various diseases and disorders, including: 1. **Cancer:** Altered expression of fibrillarin has been observed in various cancers, including leukemia, lymphoma, and solid tumors. 2. **Neurological disorders:** Fibrillarin has been linked to neurodegenerative diseases, such as Alzheimer's disease and Parkinson's disease. 3. **Blood disorders:** Mutations in the FBL gene have been associated with hematological malignancies, such as acute myeloid leukemia. 4. **Reproductive disorders:** Fibrillarin has been implicated in reproductive diseases, including infertility and miscarriage. In conclusion, fibrillarin is a critical gene that plays a pivotal role in RNA processing, ribosome biogenesis, and chromatin remodeling. Its dysregulation has been implicated in various diseases and disorders, highlighting the importance of further research into the molecular mechanisms underlying fibrillarin's functions.
