Anti-FBLL1 antibodies are used in the immunodetection of the protein fibrillarin like 1. In humans, the canonical protein has a reported length of 334 amino acid residues and a mass of 34.8 kDa. Its subcellular localization is in the nucleus. A member of the Fibrillarin protein family, Fbll1 is reported to be a S-adenosyl-L-methionine-dependent methyltransferase that has the ability to methylate both RNAs and proteins. Synonyms for this target antigen include rRNA/tRNA 2'-O-methyltransferase fibrillarin-like protein 1 and protein-glutamine methyltransferase. FBLL1 gene orthologs have been reported in the mouse, rat and bovine species. These Fbll1 antibodies are widely used in Western Blot experiments, among other applications.
