The UniProt recommended name is Ran-binding protein 3 (RANBP3). This protein functions as a cofactor in the Ran GTPase cycle, controlling the directionality of transport across the nuclear pore complex (NPC). RANBP3 is a crucial mediator in the export of proteins and RNAs from the nucleus to the cytoplasm, contributing to overall genome expression and cellular homeostasis.\u003cbr\u003e\u003cbr\u003eFunctionally, RANBP3 antibody identifies a 607-amino-acid cytoplasmic and nuclear protein that interacts with Ran GTPase, CRM1 (also known as Exportin 1), and other nucleocytoplasmic transport components. RANBP3 facilitates CRM1-dependent export of cargo molecules by stabilizing the export complex in a RanGTP-bound state. It also acts as a cofactor promoting efficient release of exported cargo upon GTP hydrolysis. Through these functions, RANBP3 ensures proper distribution of transcription factors, mRNA, and ribonucleoprotein complexes between cellular compartments.\u003cbr\u003e\u003cbr\u003eThe RANBP3 gene is located on chromosome 19p13.3 and is ubiquitously expressed across mammalian tissues. It contains an N-terminal nuclear export signal, a Ran-binding domain, and multiple leucine-rich motifs responsible for cargo recognition. RANBP3 participates in nuclear export of Smad proteins, linking it directly to TGF-beta signaling. By facilitating Smad nuclear export, it modulates transcriptional responses to growth factors and cytokines. Its activity is regulated by phosphorylation and nuclear-cytoplasmic shuttling that respond to cell cycle and signaling cues.\u003cbr\u003e\u003cbr\u003eIn addition to its export functions, RANBP3 maintains genome integrity by controlling the localization of DNA repair factors and replication regulators. It also contributes to ribosome biogenesis and mRNA surveillance by interacting with nuclear export adaptors. Dysregulation of RANBP3 has been associated with tumor progression and antiviral defense, as viruses often hijack CRM1-dependent pathways to export viral RNA and proteins.\u003cbr\u003e\u003cbr\u003eRANBP3 antibody is widely used in studies of nucleocytoplasmic transport, gene regulation, and signal transduction. It is suitable for immunoblotting, immunofluorescence, and nuclear fractionation assays to examine RANBP3 distribution and function. This antibody supports research into RNA export, TGF-beta signaling, and nuclear pore dynamics. In disease studies, RANBP3 detection helps elucidate altered nuclear transport mechanisms contributing to cancer and viral infection.\u003cbr\u003e\u003cbr\u003eStructurally, RANBP3 contains a pleckstrin homology-like domain and a Ran-binding domain that coordinate GTPase activity and CRM1 interaction. Post-translational modifications such as phosphorylation at specific serine residues regulate its subcellular localization and export efficiency.\u003c\/div\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eConnecting protein-level changes to phenotype using orthogonal readouts (genetic perturbation, transcriptomics, imaging).\u003c\/li\u003e\n\u003cli\u003eConsidering isoforms and post-translational regulation when interpreting protein-level changes.\u003c\/li\u003e\n\u003cli\u003eComparing results across species and model systems with matched controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWestern blotting:\u003c\/strong\u003e compare relative abundance and activation-state changes across conditions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunofluorescence:\u003c\/strong\u003e visualize subcellular distribution and cell-to-cell heterogeneity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eImmunohistochemistry:\u003c\/strong\u003e map target signal in tissue context and compare regions\/phenotypes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlow cytometry:\u003c\/strong\u003e quantify target-positive populations and signal shifts at single-cell resolution.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eELISA:\u003c\/strong\u003e support antibody-based quantification in assay formats where applicable.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpret changes in signal alongside appropriate controls and, when relevant, in parallel with total-protein or pathway readouts.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eSignal can reflect expression level, isoform composition, and post-translational state; interpret results in the context of your model system and stimuli.\u003c\/li\u003e\n\u003cli\u003eSpecies differences and sample matrices can influence epitope recognition; prioritize matched controls and orthogonal confirmation when feasible.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eAntibody notes:\u003c\/strong\u003e Polyclonal antibodies recognize multiple epitopes, which can broaden the epitope footprint and may increase sensitivity in some contexts.\u003c\/p\u003e\u003c!-- Sources (internal): - UniProt search — UniProt — https:\/\/www.uniprot.org\/uniprotkb?query=RANBP3 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=RANBP3 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=RANBP3 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/RANBP3 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=RANBP3+review --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"Adding 0.2 ml of distilled water will yield a concentration of 500 ug\/ml \/ 100 ug","offer_id":53047308779885,"sku":"FY13005","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_9c9f9cee-76b8-4c3f-b932-133cddce1637.jpg?v=1782237073","url":"https:\/\/www.ebiohippo.com\/products\/ranbp3-antibody-ran-binding-protein-3-bha17135907","provider":"BioHippo","version":"1.0","type":"link"}
