The capsid encapsulates the genomic dsRNA. VP2 is also involved in attachment and entry into the host cell by interacting with host ITGA4\/ITGB1 .The precursor of VP2 plays an important role in capsid assbly. First, pre-VP2 and VP2 oligomers assble to form a procapsid. Then, the pre-VP2 intermediates may be processed into VP2 proteins by proteolytic cleavage mediated by VP4 to obtain the mature virion. The final capsid is composed of pentamers and hexamers but VP2 has a natural tendency to assble into all-pentameric structures. Therefore pre-VP2 may be required to allow formation of the hexameric structures .Protease VP4 is a serine protease that cleaves the polyprotein into its final products. Pre-VP2 is first partially cleaved, and may be completely processed by VP4 upon capsid maturation..\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=VP2 - NCBI Gene search: https:\/\/www.ncbi.nlm.nih.gov\/gene\/?term=VP2 - PubMed search: https:\/\/pubmed.ncbi.nlm.nih.gov\/?term=VP2 - Ensembl search: https:\/\/www.ensembl.org\/Multi\/Search\/Results?q=VP2 - Reactome Pathway Browser: https:\/\/reactome.org\/content\/query?q=VP2 --\u003e","brand":"CUSABIO TECHNOLOGY LLC","offers":[{"title":"1 mg","offer_id":53053051535725,"sku":"CSB-RP182094V-1MG","price":2466.0,"currency_code":"USD","in_stock":true},{"title":"100 ug","offer_id":53053206364525,"sku":"CSB-RP182094V-100UG","price":729.0,"currency_code":"USD","in_stock":true},{"title":"20 ug","offer_id":53053206397293,"sku":"CSB-RP182094V-20UG","price":388.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/CSB-RP182094V-SDS.jpg?v=1772172900","url":"https:\/\/www.ebiohippo.com\/products\/recombinant-avian-infectious-bursal-disease-virus-structural-polyprotein-partial-bhp10504338","provider":"BioHippo","version":"1.0","type":"link"}
