Recombinant Human Fibrillarin Protein, GST-tagged

Cat.No. : FBL-83H
Product Overview : Recombinant Human Fibrillarin Protein (1-321) is produced by E. coli expression system. This protein is fused with a GST tag at the N-terminal.
Description : Human recombinant fibrillarin (residues 2-321; Genbank Accession # NM_001436; MW= 61.3 kDa) expressed as an N-terminal GST-fusion protein in E. coli. Fibrillarin is a component of nucleolar ribonucleoprotein complexes including snoRNPs (small nucleolar ribonucleoproteins) and Cajal bodies. As part of the C/D snoRNPs, fibrillarin functions as the catalytic subunit in the 2’-O methylation of ribosomal RNAs1. In addition, fibrillarin has recently been shown to catalyze methylation of histone H2A glutamine-104, a modification restricted to the nucleolus and linked to RNA Pol I transcriptional activity on rDNA3. A distinct protein subcomplex comprising fibrillarin, SF2A-p32 and the argininine methyltransferases PRMT1 and PRMT5 has been described4 and fibrillarin’s N-terminal glycine and arginine-rich (GAR) domain, including in the context of full-length fibrillarin5, is a substrate for various PRMTs.
