GCLC catalyzes the first and rate-limiting step in glutathione (GSH) biosynthesis, forming gamma-glutamylcysteine from glutamate and cysteine. This enzyme plays an essential role in maintaining redox homeostasis, detoxifying reactive oxygen species (ROS), and protecting cells from oxidative stress. GCLC is expressed ubiquitously, with highest levels in liver, kidney, and lung, where glutathione metabolism is most active.\u003cbr\u003e\u003cbr\u003eStructurally, GCLC is a 73 kDa cytosolic enzyme that functions as the catalytic component of the heterodimeric glutamate-cysteine ligase complex, together with the modifier subunit GCLM. It contains ATP-binding and substrate-recognition domains that mediate the ligation reaction. GCLC belongs to the ATP-dependent ligase family and serves as the principal control point in GSH biosynthesis. Co-localization studies show cytoplasmic distribution in metabolically active tissues, aligning with its antioxidant role.\u003cbr\u003e\u003cbr\u003eFunctionally, GCLC maintains cellular antioxidant defenses by providing the precursor for glutathione synthesis. Glutathione serves as a cofactor for numerous detoxification enzymes, including glutathione peroxidases and glutathione S-transferases. Through GSH production, GCLC supports redox regulation, protein thiol homeostasis, and protection against electrophilic stress. In immune cells, GCLC-derived glutathione regulates T-cell activation and macrophage inflammatory responses. Known substrates include L-glutamate, L-cysteine, and ATP.\u003cbr\u003e\u003cbr\u003eDeficiency or dysregulation of GCLC results in decreased glutathione levels, leading to oxidative stress, hemolytic anemia, and liver dysfunction. Mutations in GCLC are associated with glutathione synthetase deficiency and neurological disorders linked to oxidative damage. Overexpression is observed in certain cancers, conferring chemoresistance through enhanced antioxidant capacity. Pathway associations include glutathione metabolism, oxidative stress response, and xenobiotic detoxification. During development, GCLC supports organogenesis by protecting proliferating cells from oxidative injury.\u003cbr\u003e\u003cbr\u003eThe GCLC antibody from\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=GCLC - NCBI Gene search — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=GCLC - Ensembl search — Ensembl — https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=GCLC - Human Protein Atlas search — HPA — https:\/\/www.proteinatlas.org\/search\/GCLC - PubMed (review) — NLM — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=GCLC+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":53047324246381,"sku":"FY13385","price":449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/get_image_d302850d-20b0-438d-ba46-4c4241dd08b6.jpg?v=1782237111","url":"https:\/\/www.ebiohippo.com\/products\/gclc-antibody-glutamate-cysteine-ligase-catalytic-subunit-bha17136287","provider":"BioHippo","version":"1.0","type":"link"}
