The UniProt recommended name is Cyclic AMP-responsive element-binding protein 3 (CREB3). This ER membrane-bound transcription factor controls gene expression related to protein folding, trafficking, and secretion.\u003cbr\u003e\u003cbr\u003eFunctionally, CREB3 antibody identifies a 371-amino-acid protein anchored in the ER membrane with a cytoplasmic basic leucine zipper (bZIP) domain. Upon ER stress, the N-terminal transcriptional domain of CREB3 is cleaved and translocated to the nucleus, where it activates target genes involved in secretion and Golgi maintenance. CREB3 also regulates acute phase response genes and collagen biosynthesis.\u003cbr\u003e\u003cbr\u003eThe CREB3 gene is located on chromosome 9p13.3 and is highly expressed in secretory tissues such as liver, pancreas, and intestine. It plays a central role in adapting to increased secretory load and maintaining ER homeostasis under stress conditions.\u003cbr\u003e\u003cbr\u003ePathologically, dysregulation of CREB3 contributes to metabolic disorders, neurodegeneration, and cancer progression by disturbing ER stress response pathways. Overexpression can enhance tumor invasion by modulating extracellular matrix and stress-related signaling genes. Research using CREB3 antibody supports studies in transcriptional regulation, ER stress, and secretory pathway biology.\u003cbr\u003e\u003cbr\u003eCREB3 antibody is validated for western blotting, immunofluorescence, and immunohistochemistry to detect transcription factors and stress response regulators. \u003cbr\u003e\u003cbr\u003eStructurally, Cyclic AMP-responsive element-binding protein 3 contains a bZIP domain for DNA binding and dimerization, along with a luminal stress-sensing region. This antibody enables investigation of CREB3's role in ER stress signaling and transcriptional control.\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\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=CREB3 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=CREB3 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=CREB3 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/CREB3 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=CREB3+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":53047318315373,"sku":"FY13192","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_1ef89a55-2510-4fa6-bfd0-7d6ccba7a40c.jpg?v=1782237069","url":"https:\/\/www.ebiohippo.com\/products\/creb3-antibody-cyclic-amp-responsive-element-binding-protein-3-bha17136094","provider":"BioHippo","version":"1.0","type":"link"}
