Essential for the initial attachment to heparan sulfate moities of the host cell surface proteoglycans. Involved in fusion of viral and cellular membranes leading to virus entry into the host cell. Following initial binding to its host receptors, membrane fusion is mediated by the fusion machinery composed at least of gB and the heterodimer gH\/gL. May be involved in the fusion between the virion envelope and the outer nuclear membrane during virion egress.\u003c\/p\u003e\u003ch2\u003eResearch relevance and current trends\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReagent standardization: using recombinant proteins as reference materials for quantitative calibration and cross-study comparability.\u003c\/li\u003e\n\u003cli\u003eInteraction-focused studies: mapping binding partners, affinity changes, and structure–function relationships across variants or domains.\u003c\/li\u003e\n\u003cli\u003eMulti-omic readouts: combining recombinant perturbations with transcript, protein, and functional endpoints to connect mechanism to phenotype.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eCommon research applications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eAssay development and validation: use as a defined input or standard where protein identity is required.\u003c\/li\u003e\n\u003cli\u003eBinding studies: evaluate interaction strength and specificity using plate-based or biophysical formats.\u003c\/li\u003e\n\u003cli\u003eCell-response profiling: add protein to cultured cells and interpret downstream marker changes with appropriate controls.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eInterpretation is most robust when signal changes are evaluated relative to matched controls (buffer-only, unrelated protein controls, or pathway controls) and when readouts are compared across dose and time.\u003c\/p\u003e\u003ch2\u003eNotes for experimental interpretation\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIsoforms and PTMs can influence binding and activity; ensure the expressed region and expression system match your experimental needs.\u003c\/li\u003e\n\u003cli\u003eSpecies differences may affect receptor binding or antibody recognition; confirm species\/source alignment with your model.\u003c\/li\u003e\n\u003cli\u003eUse concept-level controls such as negative controls (no protein), matrix controls, or orthogonal readouts to support conclusions.\u003c\/li\u003e\n\u003c\/ul\u003e\u003c!-- Sources (internal): - UniProt keyword search: https:\/\/www.uniprot.org\/uniprotkb?query=gB - NCBI Gene search: https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=gB - PubMed search: https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=gB - Ensembl search: https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=gB - Reactome Pathway Browser: https:\/\/reactome.org\/content\/query?q=gB --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53053081223533,"sku":"CSB-EP309330RKC-1MG","price":2466.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53053263708525,"sku":"CSB-EP309330RKC-100UG","price":578.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53053263741293,"sku":"CSB-EP309330RKC-20UG","price":306.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-EP309330RKC-SDS.jpg?v=1772173022","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-rhesus-cytomegalovirus-envelope-glycoprotein-b-gb-partial-bhp10505220","provider":"BioHippo","version":"1.0","type":"link"}
