Encoded by the GBE1 gene on chromosome 3p12.3, this enzyme catalyzes the formation of glycogen's highly branched structure, which enhances solubility and allows rapid synthesis and mobilization of glucose. GBE1 is a crucial metabolic regulator in liver, skeletal muscle, and other tissues involved in energy storage and glucose homeostasis.\u003cbr\u003e\u003cbr\u003eStructurally, GBE1 is a 702-amino-acid cytosolic enzyme of approximately 80 kilodaltons that belongs to the glycoside hydrolase family 13. It contains a central catalytic domain with the conserved Asp-Glu-Asp catalytic triad and carbohydrate-binding modules that enable glucan chain recognition and rearrangement. By transferring short alpha-1,4-linked oligosaccharide chains to alpha-1,6 positions, GBE1 generates the branch points that define glycogen's compact and accessible configuration.\u003cbr\u003e\u003cbr\u003eThe GBE1 antibody is widely used in glycogen metabolism, endocrinology, and neuromuscular research to study carbohydrate storage, enzymatic regulation, and metabolic disease mechanisms. Western blot analysis detects an 80 kilodalton band corresponding to GBE1, while immunofluorescence shows diffuse cytoplasmic staining, particularly in hepatocytes and myocytes. This antibody supports investigations of glycogen biosynthesis and the enzymatic defects underlying glycogen storage disorders.\u003cbr\u003e\u003cbr\u003eMutations in GBE1 cause Glycogen Storage Disease Type IV (Andersen disease) and its non-lethal variant, adult polyglucosan body disease (APBD). These disorders are characterized by abnormal glycogen accumulation and progressive neuromuscular or hepatic dysfunction. Reduced GBE1 activity leads to poorly branched glycogen with decreased solubility and impaired mobilization. The GBE1 antibody provides a reliable tool for studying enzyme expression and activity in models of metabolic disease, helping to elucidate molecular mechanisms that govern glycogen structure and energy regulation.\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=GBE1 - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=GBE1 - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=GBE1 - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/GBE1 - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=GBE1+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":53047305535853,"sku":"FY12899","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_a83ead33-7cce-4b0f-b22d-451ff70373fe.jpg?v=1782237051","url":"https:\/\/www.ebiohippo.com\/products\/gbe1-antibody-1-4-alpha-glucan-branching-enzyme-1-bha17135801","provider":"BioHippo","version":"1.0","type":"link"}
