Interphotoreceptor retinol-binding protein is a large glycoprotein known to bind retinoids and found primarily in the interphotoreceptor matrix of the retina between the retinal pigment epithelium and the photoreceptor cells. It is thought to transport retinoids between the retinal pigment epithelium and the photoreceptors, a critical role in the visual process. The human IRBP gene is approximately 9.5 kbp in length and consists of four exons separated by three introns. The introns are 1.6-1.9 kbp long. The gene is transcribed by photoreceptor and retinoblastoma cells into an approximately 4.3-kilobase mRNA that is translated and processed into a glycosylated protein of 135,000 Da. The amino acid sequence of human IRBP can be divided into four contiguous homology domains with 33-38% identity, suggesting a series of gene duplication events. In the gene, the boundaries of these domains are not defined by exon-intron junctions, as might have been expected. The first three homology domains and part of the fourth are all encoded by the first large exon, which is 3,180 base pairs long. The remainder of the fourth domain is encoded in the last three exons, which are 191, 143, and approximately 740 base pairs long, respectively.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eComparative expression profiling across cell types, tissues, or perturbations (e.g., drug treatment, genetic editing, or differentiation).\u003c\/li\u003e \u003cli\u003eSubcellular localization and trafficking studies, including co-localization with pathway markers in microscopy-based assays.\u003c\/li\u003e \u003cli\u003eIntegration of protein-level measurements with transcriptomics or proteomics to relate abundance to regulation and phenotype.\u003c\/li\u003e \u003c\/ul\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e \u003cul\u003e \u003cli\u003eWestern blotting: researchers commonly compare relative signal levels across conditions and use appropriate negative\/positive controls for interpretation.\u003c\/li\u003e \u003cli\u003eFlow cytometry: researchers commonly compare relative signal levels across conditions and use appropriate negative\/positive controls for interpretation.\u003c\/li\u003e \u003cli\u003eELISA: researchers commonly compare relative signal levels across conditions and use appropriate negative\/positive controls for interpretation.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eInterpretation should account for antibody-dependent factors such as epitope accessibility, isoforms, and sample preparation differences across workflows.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eIsoforms and PTMs:\u003c\/strong\u003e many targets have multiple isoforms and post-translational modifications that can shift apparent signal or localization; interpret bands\/signals accordingly.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eEpitope context:\u003c\/strong\u003e binding can depend on protein conformation and sample processing; region information in the title\/immunogen can help anticipate what may be detected.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSpecies differences:\u003c\/strong\u003e predicted or validated reactivity may vary by ortholog sequence and sample context; confirm in your model system.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eControl concepts:\u003c\/strong\u003e include negative controls (no-primary\/isotype), and where possible genetic controls (KO\/KD) or independent antibodies to strengthen conclusions.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProtKB entry P10745 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/P10745 - Gene search: RBP3 — NCBI Gene — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=RBP3 - Ensembl search: RBP3 — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=RBP3 - PubMed search: RBP3 antibody — PubMed — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=RBP3+antibody - Reactome search: RBP3 — Reactome — https:\/\/reactome.org\/content\/query?q=RBP3 --\u003e","brand":"NSJ Bioreagents","offers":[{"title":"0.5mg\/ml if reconstituted with 0.2ml sterile DI water \/ 100 ug","offer_id":53046455075181,"sku":"RQ7792","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_a4aa56db-1f9d-4948-9438-8bf512eeeb02.jpg?v=1772000726","url":"https:\/\/www.ebiohippo.com\/products\/irbp-antibody-rbp3-retinol-binding-protein-3-bha17129355","provider":"BioHippo","version":"1.0","type":"link"}
