Functional context (as provided): 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). . Reported cellular localization context: Nucleus, nucleolus . Fibrillar region of the nucleolus. Tissue expression notes (as provided): In fetal tissues, highly expressed in brain, detectable in lung and liver, but not in kidney. In adult tissues, expressed ubiquitously in the brain, detectable in the heart, liver, spleen, thymus, prostate, testis, ovary, small intestine and colon. The type A isoforms seem to be expressed predominantly in fetal brain whereas type B isoforms are expressed abundantly in both fetal and adult brain. .\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eResearch context keywords from the source record include: Actin Assembly,Actin, etc.,Cytoskeleton,Cytoskeleton\/ECM,Extracellular Matrix,Microfilaments,Signal Transduction,Structures.\u003c\/li\u003e\n\u003cli\u003eCurrent studies often focus on connecting target abundance\/localization to pathway perturbations across models, tissues, and cell states.\u003c\/li\u003e\n\u003cli\u003eQuantitative and multiplexed assays (e.g., imaging + immunoblot panels) are commonly used to compare phenotypes across conditions and time-courses.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eWestern blotting (WB):\u003c\/strong\u003e assess relative target abundance across samples, treatments, or time-points.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry (IHC):\u003c\/strong\u003e evaluate spatial distribution of target-positive staining in tissue architecture.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunofluorescence\/ICC (IF\/ICC):\u003c\/strong\u003e visualize subcellular localization patterns and cell-to-cell heterogeneity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e quantify target-positive populations and compare shifts in marker distributions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunoprecipitation (IP):\u003c\/strong\u003e enrich target complexes for downstream immunoblot or interaction analyses.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eWorkflow ideas (metafield): Validate FBL antibody specificity using KO\/KD control samples (WB\/IF\/IHC as appropriate), Detect FBL expression by Western blot in cell or tissue lysates, Detect FBL in FFPE tissue sections by immunohistochemistry, Localize FBL by immunofluorescence\/immunocytochemistry in cultured cells, Quantify FBL-positive cells by flow cytometry in single-cell suspensions, Enrich FBL by immunoprecipitation from lysates for downstream analysis\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eConsider isoforms and post-translational modifications (PTMs) that may shift apparent molecular weight or epitope accessibility.\u003c\/li\u003e\n\u003cli\u003eApparent molecular weight may vary by sample type and processing (observed MW: 70 kDa; calculated MW: 33784 MW).\u003c\/li\u003e\n\u003cli\u003eControl concepts: include appropriate negative controls (e.g., isotype, KO\/KD samples) and orthogonal validation when feasible.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eAdditional product details (from the source record)\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMolecular weight (observed):\u003c\/strong\u003e 70 kDa\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCellular localization (provided):\u003c\/strong\u003e Nucleus, nucleolus .
