Fbl Gene Summary [Rat]
Predicted to enable several functions, including ATPase binding activity; S-adenosylmethionine-dependent methyltransferase activity; and TFIID-class transcription factor complex binding activity. Predicted to be involved in box C/D sno(s)RNA 3'-end processing; ribosome biogenesis; and snoRNA localization. Predicted to act upstream of or within sno(s)RNA metabolic process. Located in Cajal body; chromosome; and dense fibrillar component. Orthologous to human FBL (fibrillarin). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Fbl often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
