GLUL refers to a protein target that is studied across multiple biological contexts; annotations and nomenclature can vary by species and isoform. This product corresponds to the Cricetulus griseus (Chinese hamster) (Cricetulus barabensis griseus) sequence context, which can be important when comparing homologs or orthologs across model systems. For curated functional annotations, domains, and sequence features, consult primary databases (e.g., UniProt\/NCBI) and the recent literature for the specific organism and isoform.\u003c\/p\u003e \u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eLinking protein expression or modification states to neuronal activity, synaptic plasticity, and circuit phenotypes.\u003c\/li\u003e \u003cli\u003eStudying receptor\/ligand or scaffolding interactions that influence synapse organization and signaling.\u003c\/li\u003e \u003cli\u003eDeveloping quantitative assays to track neurodegeneration- or injury-associated molecular changes.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eRelevance:\u003c\/strong\u003e Glutamine synthetase that catalyzes the ATP-dependent conversion of glutamate and ammonia to glutamine. Its role depends on tissue localization: in the brain, it regulates the levels of toxic ammonia and converts neurotoxic glutamate to harmless glutamine, whereas in the liver, it is one of the enzymes responsible for the removal of ammonia. Essential for proliferation of fetal skin fibroblasts. Independently of its glutamine synthetase activity, required for endothelial cell migration during vascular development: acts by regulating membrane localization and activation of the GTPase RHOJ, possibly by promoting RHOJ palmitoylation. May act as a palmitoyltransferase for RHOJ: able to autopalmitoylate and then transfer the palmitoyl group to RHOJ. Plays a role in ribosomal 40S subunit biogenesis.\u003c\/p\u003e \u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eEnzyme activity assays and kinetics measurements with defined substrates\/cofactors.\u003c\/li\u003e \u003cli\u003eInhibitor, activator, or substrate screening in biochemical assay formats.\u003c\/li\u003e \u003cli\u003eStructure–function analysis to interpret how sequence changes impact catalytic performance.\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003eIn quantitative assay development, changes in binding or activity readouts are typically interpreted relative to appropriate negative\/positive controls and, where possible, orthogonal assay formats that support the same conclusion.\u003c\/p\u003e \u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e \u003cli\u003eRecombinant constructs may represent a defined region (domain) rather than the full-length protein; interpret results in the context of the expressed region.\u003c\/li\u003e \u003cli\u003eTag or fusion elements can aid purification and detection but may influence binding surfaces or oligomerization; consider tag controls when relevant.\u003c\/li\u003e \u003cli\u003eSpecies and isoform differences can affect interaction partners and post-translational modifications; align experimental controls to the intended biological context.\u003c\/li\u003e \u003cli\u003eE. coli expression can limit eukaryotic post-translational modifications; for modification-dependent biology, interpret results accordingly.\u003c\/li\u003e \u003c\/ul\u003e \u003c!-- Sources (internal): - UniProtKB entry for P04773 — UniProt — https:\/\/www.uniprot.org\/uniprotkb\/P04773\/entry - NCBI Gene search (GLUL) — NCBI — https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=GLUL - PubMed search (GLUL) — NCBI — https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=GLUL - RCSB PDB search (GLUL) — RCSB PDB — https:\/\/www.rcsb.org\/search?query=GLUL - Reactome Pathway Browser — Reactome — https:\/\/reactome.org\/ --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53065295200621,"sku":"CSB-EP009553DXUa0-1MG","price":2466.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53065440526701,"sku":"CSB-EP009553DXUa0-100UG","price":729.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53065440559469,"sku":"CSB-EP009553DXUa0-20UG","price":388.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP009553DXUa0-SDS.jpg?v=1772476555","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-cricetulus-griseus-glutamine-synthetase-glul-bhp10509627","provider":"BioHippo","version":"1.0","type":"link"}
