ターゲット情報

  • 機能

    S-adenosyl-L-methionine-dependent methyltransferase that has the ability to methylate both RNAs and proteins. Involved in pre-rRNA processing by catalyzing the site-specific 2'-hydroxyl methylation of ribose moieties in pre-ribosomal RNA. Site specificity is provided by a guide RNA that base pairs with the substrate. Methylation occurs at a characteristic distance from the sequence involved in base pairing with the guide RNA. Also acts as a protein methyltransferase by mediating methylation of 'Gln-105' of histone H2A (H2AQ104me), a modification that impairs binding of the FACT complex and is specifically present at 35S ribosomal DNA locus (PubMed:24352239).
  • 配列類似性

    Belongs to the methyltransferase superfamily. Fibrillarin family.
  • 翻訳後修飾

    By homology to other fibrillarins, some or all of the N-terminal domain arginines are modified to asymmetric dimethylarginine (DMA).
  • 細胞内局在

    Nucleus, nucleolus. Fibrillar region of the nucleolus.

    ab5821 staining Fibrillarin in HeLa cells. The cells were fixed with 4% paraformaldehyde (10 min), permeabilized with 0.1% PBS-Triton X-100 for 5 minutes and then blocked with 1% BSA/10% normal goat serum/0.3M glycine in 0.1%PBS-Tween for 1h. The cells were then incubated overnight at 4°C with ab5821 at 0.1µg/ml and ab7291, Mouse monoclonal [DM1A] to alpha Tubulin - Loading Control. Cells were then incubated with ab150081, Goat polyclonal Secondary Antibody to Rabbit IgG - H&L (Alexa Fluor® 488), pre-adsorbed at 1/1000 dilution (shown in green) and ab150120, Goat polyclonal Secondary Antibody to Mouse IgG - H&L (Alexa Fluor® 594), pre-adsorbed at 1/1000 dilution (shown in pseudocolour red). Nuclear DNA was labelled with DAPI (shown in blue).

    Immunofluorescent imaging of human cells (U2OS) with ab5821 reveals highly specific localisation to the dense fibrillar component (DFC) of the nucleolus associated with the initial ribosomal RNA (rRNA) precursor. The nucleolar protein fibrillarin is located primarily in the DFC.  Blue is hoechst staining of the nucleus, green is ab5821 used at 1/100, merge image demonstrates exclusively nuclear localisation.  

    IF was performed with a standard paraformaldehyde technique (fixed in PBS buffered PFH 4% for 5 minutes, permeabilised with 0.5% triton-PBS for 5 minutes, blocked with 5% milk / 0.2% tween for one hour.  Primary antibody used at 1/100 in 5% milk / 0.2% TWEEN for one hour, secondary antibody Alexa 488 for 30 minutes.  All blocking and incubation steps carried out at 37 degrees C.
